A. How to set text display on BMW:
Please note: The Gateway Lite BT is capable of displaying text only on BMW radios
-Gateway Lite BT is not capable of full menu browsing, you will only have music information
display
-There are 3 different types of display available (Radio; MID and Navigation) and each
requires a different configuration, so you will need to change settings after installation
To set text from the text selection menu:
1. Turn the Radio ON and select the Gateway (CD-Changer)
2. Disconnect all devices from the Gateway and wait until CD5 / Track99 is displayed on the radio
3. Keep the FF (Fast Forward) button pressed for at least 10 seconds, then release.
4. The display will show ‘Disc 1 / track 01’within 3 seconds (indicating that you are in text
selection mode)
5. By pressing the Next track button, you can choose Tracks 02 through 04 which represent
different screen modes (e.g. MID, Radio). Please note: Track 01 is non-Text Mode
6. After choosing the mode you prefer, press FF (Fast Forward) to confirm and save the selection.
Or, by pressing the REW (Rewind) you can exit Text selector and discard changes.
7. If the text mode selection is correct ‘AUX GW’will appear on the display
8. If the text selection was not successful, try again from step #3 and chose another option. Some
radios will work only with a specific track setting.
Please note: If selecting Tracks 02 through 04 fail to display text, the radio might not support text
display for one of the following reasons:
-The radio is manufactured by Becker (That information is displayed on the label on tuner, there
is no specification on the radio to reveal it.)
-The Head Unit is attached to a phone module or is prepared for one. This issue can be
encountered on the Business radio.

On some BMW radios, there is an ‘M’button between the Next Track and Previous Track buttons to
change the function to FF (Fast Forward) and REW (Rewind).
On these radios, use the ‘M’button for the text activation procedure:
1. Turn the Radio ON and select the Gateway (CD-Changer)
2. Disconnect all devices from the Gateway and wait until CD5 / Track99 is displayed on the radio
3. Press the ‘M’button on the radio, an ‘M’should appear on the radio display
4. Keep the FF (Fast Forward) button pressed for at least 10 seconds, then release.
5. The display will show ‘Disc 1 / track 01’ within 3 seconds (indicating that you are in text
selection mode)
6. Press the ‘M’button on the radio to select Next/Back function
7. By pressing the Next track button, you can choose Tracks 02 through 04 which represent
different screen modes (e.g. MID, Radio). Please note: Track 01 is non-Text Mode
8. After choosing the mode you prefer, press ‘M’then press FF (Fast Forward) to confirm and
save the selection. Or, by pressing the REW (Rewind) you can exit Text selector and discard
changes.
9. If the text mode selection is correct ‘AUX GW’ will appear on the display
10. If the text selection was not successful, try again from step #3 and chose another option. Some
radios will work only with a specific track setting.
B. How to set text display on Toyota
Some Toyota radios are capable of displaying basic text information. To show these press “DISP”, “TXT”
or “TEXT” button on the radio. If you have any of these buttons on the radio and the text information
does not appear on the display, your radio is not capable of displaying such information.

C. How to get/generate the GW_EES.BIN file:
The GW_EES.BIN file provides important information regarding
-the exact firmware version
-the basic settings (text, or car configuration)
-connected devices (like DAB+G)
To generate the file you need to have a simple USB thumb drive which is
-formatted to FAT 32
-has only one partition
-has at least one playable music content on it
You need to
1. Power the system ON (radio, ignition)
2. Connect the USB drive to the Gateway (it starts to operate)
3. Select the Gateway as a source (eg. CD-Changer)
4. Turn the whole system OFF, remove the key from the ignition
5. Wait for 2 minutes
6. Turn the system ON (e.g. radio)
7. The USB will start to operate
8. Wait 10 seconds, disconnect and check the content on a PC. The GW_EES.BIN should be
present in the root folder.
Please note: If the file is not available, please use a different USB stick and repeat the steps above.
The firmware version can be checked if you open the file with the Notepad (or similar) application. In
the first line of the file you will see (something similar to) the following:
On the picture above, the hardware runs on firmware version 3.00. Please check if a newer firmware
is available for download. If yes: please update –this is highly recommended.
Please note: Although we do support playing music content from a USB hard disk drive, for the
firmware update (volume settings) please use a USB flash stick/pen drive.

C. Is there a limit on the number of tracks the Gateway can handle?
There is no limit referring to track numbers. You can have as many as you want if the overall size of
your music not larger than the maximum capacity (256 GB) that we offer.
E. Is there any recommendation on how to organize music?
The Lite BT is a non-text capable device (except BMW or some Toyota where id3 tags can be displayed)
so we recommend the use of USB drives that do not exceed 64 GB in size, because it is simply too
difficult to search through music above this size.
The recommended structure for music is Genre Artist Album. Example:
F. What is the free brown cable on the Gateway car harness?
The free brown lead on the Gateway car harness needs to be connected to the phone mute pin of the
car radio (if applicable). This cable is causing the radio to mute the actual media playback when Radio
or simple CD-mode is selected.
Please note: There is no free brown lead on BMW car harnesses (GBL3BM1/BM4)
G. Where to connect the mute wire on the radio
The separate brown cable needs to be connected to the Phone mute pin of the radio.
The position of the pin is different with each radio type, therefore check the Pin out diagram of the
radio. When removed from the Dashboard, there must be a diagram on the radio. If not, the quickest
solution is to ‘google’it. We are ready to help if you get stuck with this, but please be aware that it
might take some time to answer such questions correctly.
H. What is the free black cable on the Gateway car harness?
The free black lead on the Gateway harness must be grounded properly (or connected to the chassis
of the car –NOT the radio). This lead doesn’t have to be connected in BMWs. If this cable is not
grounded properly in an Audi or a VW, the Gateway might not power up.
Please note: There is no free black lead on some car harnesses (Mazda, Toyota)

I. The Gateway Lite (GWLxxx, GBLxxx) volume is distorted/lower than my Radio or CD
player. Is there any option to change the volume output levels?
This could happen ‘relatively’easily because all cars, chassis are different. It can be small, medium, big
or large, could come with 4 or 12 speakers. Therefore we use default settings that work in most cases.
If in your case it does not and the volume is too loud, distorted or low compared to other sources,
please go to the Dension website and download the volume configuration files and read the specific
Knowledgebase article:
http://www.dension.com/knowledge-base/the-gateway-lite-gwlxxx-gblxxx-volume-is-distorted-
lower-than-my-radio-or-cd-player-0
Follow these steps:
1. Unzip the volume package file
2. Select and copy the appropriate configuration file from iPod, USB or AUX & A2DP
folder to the root of a USB flash drive where you have at least one playable content.
Use 0dB / +6dB files if the volume is low or -1dB/-20bB if the volume is distorted
3. Connect the USB drive to the Gateway while it is powered up
4. The volume configuration procedure takes about 2 seconds. When finished, the next
song will be audible on your car’s speakers
5. Turn the Audio System OFF, remove the ignition key and wait for about 20 seconds.
Turn the Audio System back ON
6. Test your Audio System. If the volume output is still not optimal, please repeat steps
2-5 with another volume configuration file
Please note: Although we do support playing music content from a USB hard disk drive, for the
firmware update (volume settings) please use a USB flash stick/pen drive.

K. iPod/iPhone not recognized
This usually happens if there is a problem with the iPod / iPhone or Dock cable. Before replacing
anything, you need to try the following:
Make sure there is music on the Apple device
Reboot the Apple device (if it is an iPhone, close all apps before rebooting)
Update the iPod/iPhone if a newer iOS version is available
Check the charging status. If there is no charging the problem might be installation related
(no ground cable connected on VW/Audi)
Test the system with a different Apple product
Disconnect and reconnect the Gateway hardware from the power
Check the Dension website. There might be an available update for the Gateway
L. USB compatibility
Flash Memory and Hard Disk Drives
File system: FAT32
Storage capacity: up to 256 GB of music content
Music format:
MP3
MPEG1 Layer 3 : 32; 44,1; 48 kHz (32 - 320kbps);
MPEG2 Layer 3 : 16; 22,05; 24 kHz (8 - 160kbps);
MPEG2.5 Layer 3 : 8; 11.025; 12 kHz (8 -160 kbps) from 96 kb/s to 320 kb/s;
MP3 Variable Bit Rate (VBR) (up to 320kb/s).
WMA 4 - 44.1 kHz at sample rates up to 320 kb/s. Except for DRM protected files.
WAV (16 bit, uncompressed PCM)
We recommend the use of branded USB drives (TDK, Kingston, Sandisk, Transcend etc.).
M. USB does not work/Gateway does not see the connected device:
In some cases the USB drive will only flash continuously or flash just once (if there is a status indicator
LED on it) but will not play audio. When USB is connected to Gateway, it starts to index the content
immediately (LED on the USB is flashing constantly) in order to find and select the tracks as quickly as
possible. If a large music content is available (4GB or above) it may take a few minutes during which
the drive cannot be accessed, so playback might not be available, or when the user changes the music
content on the USB the Gateway might not find the previously indexed songs.
So, if there is a problem with the USB playback, do the following:
-wait for a few minutes, then the playback should start
-turn the system OFF, remove the key from the ignition, wait for 2 minutes, and turn the
system back ON –the playback should start immediately
-delete all ‘.bin’files from the root folder of the USB drive (the index files might be damaged)
-download the ‘Gateway Indexer software’(Windows only) from our website. It indexes the
music files same way as the Gateway, but faster

-make sure the files are not write protected (to do so use check the files on a PC)
Please note: The write protection cannot be switched off on certain Sony USB. Such USB drives cannot
be used with Gateway Lite or Lite BT.
If nothing helps you need to get some details about the USB drive:
-Size (we are fine up to 256 GB)
-Brand (cheap drives are not always supported due to low quality memory chips on board)
-File system (only FAT32 is supported)
-Partition: only one (!) partition is supported. Some USB drives come with free backup and
other options which use a separate partition, that could cause the recognition failure
-Check if an aftermarket extension cable is used
-Try the system with another USB device with only a few files on it
N. Phone compatibility
We are constantly working on our compatibility chart, however there are still quite a few untested
models. But since our new BT devices have been equipped with the latest BT chip on board, the
Gateways work fine with most of the phones (e.g. iOS, Android, Blackberry, Bada). There are some
very specific local phones from Verizon or AT&T we were never able to test before. If you have any
feedback on phones working fine, please share the info (!).
The current chart can be downloaded from http://www.dension.com/compatibility
O. Phone issues
The Gateway Lite BT offers both HFP and A2DP features. Since there is no text option, there will be no
information on the radio screen upon receiving or making a phone call.
Frequently asked questions regarding telephony:
-Microphone volume is low: press the next track button during the phone call, letting you to
choose from 10 different volume values (a beep will be audible via the speakers during the
volume setup process). If you find the optimal sound level, you can leave it in that position and
it will be saved automatically when the phone connection is severed
-Phone does not connect: In rare cases it might be somewhat difficult to pair the phone to the
Gateway Lite BT device. In such cases, please ask to turn the BT option OFF on the phone,
reboot it and try again. If still no luck, please disconnect and reconnect the Gateway Lite BT
from power. If it did not help, please check if a new firmware is available for the Gateway Lite
BT and/or the phone (!). Additionally testing another phone is highly recommended to find out
if the problem is related to this specific phone or not
-A2DP volume: The volume can be changed similarly to the other sources, like iPod, USB. The
volume configuration files need to be downloaded from our website to change default settings
using a USB drive (AUX level has to be increased or decreased)

P. No sound on a BMW –only control
There might be 2 specific root causes to this issue:
-The car has a DSP unit installed
-The CD-Changer plug has not been connected correctly on GBL3BM1 (17-pin –also known
as Round-pin connector)
DSP: If the car has DSP, the device is not compatible, due to the design and architecture of the
Gateway. DSP systems require a digital input but the Gateway provides analogue output only, thus
there will be no sound, only control. The DSP unit is rare, and there is no indication of it on the radio.
Check the Tuner to tell: if there is coax connector on it, it is a DSP based system
CD-changer plug: The CD-Changer plug is a separate cable (comes with the 17 PIN plug) which ends in
a 10 pin white ‘molex’connector. This connector can be connected 2 ways to the head unit’s CD-
Changer port. If the radio connects to the Gateway but there is no sound, it might indicate improper
installation. Rotate the white connector by 180°and plug it back in.
Q. Other issues (Gateway is not recognized, Alternator noise)
Gateway is not recognized: This could happen if the ground cable is not connected (in case of VW or
Audi) or the installation is incorrect (not easy to do it wrong but… happens). Another cause could be a
damaged cable, preventing the car configuration resistor from operating (it will set it to BMW)
Alternator noise: This is an extremely rare problem. If it happens, it means there is an issue with the
cable or the hardware. The whole package has to be replaced (HW and car harness).
R. Firmware update
We constantly improve our firmware, so it is highly recommended to perform a firmware update first,
if an issue/problem arises. The update procedure on devices with a USB port is simple.
Extract the G3AH_UPD.ROM file from the update package and copy it to the root of a USB flash drive,
then connect the USB drive to the Gateway Lite when it is powered up. If there is an iPod connected
to the Gateway Lite you can leave in any playback mode or status, you do not need to disconnect or
stop playback.
Update procedure will start automatically within a few seconds and takes approximately 1 minute. Do
not disconnect the USB drive within this time. During the update the head unit (car stereo) might turn
to tuner mode while the Gateway restarts.
When finished, change the source to CD-Changer to use the Gateway again.
After a successful update G3AH_UPD.ROM is deleted from the USB flash drive and the GW_EES.BIN
file will be written containing the new software version.

Gateway Lite BT
13
If the firmware update was not successful, that could mean:
-there was no music content on the USB drive, so the Gateway Lite BT did not recognize it
-there were more than one partitions on the USB drive
-the USB drive was formatted to NTFS (or any other than FAT32)
-the updated was already installed on the Gateway => check the GW_EES.BIN
If the device is not functional after the update: (This usually happens if the user disconnects the USB during the update
process or the power has been switched off during the update)
-try to downgrade to the previous version
-disconnect the device from power and reconnect
-Check the system. If any of the functions work (USB, BT, iPod) send us the GW_EES.BIN. It
is likely that something went very bad –but we need to know exactly what
S. BMW-specific issues (volume changing, CDC cannot be selected)
On BMW, it happens quite often that they forget to disconnect the original CD-Changer properly.
Please note: The installer needs to disconnect all cables physically at the CD-Changer (2 separate
wires), otherwise they will experience strange issues like:
-Volume changes automatically/randomly within 10-15 seconds
-CD-Changer source can or cannot be selected but even if you select it, you are back to
radio mode within 2-3 seconds
-Function buttons are not or not fully working (e.g. FFW)
-You cannot enter to the Text mode selector menu
T. Phone pairing procedure takes too long
On Gateway Lite BT, the pairing procedure sometimes requires more time than normal. You may need
to try pairing from the phone menu for 2-3 minutes. The causes could be:
-the hardware is ready for pairing in a certain time period (it searches for earlier connected
phones for 30-40 seconds and for 20-25 seconds for newly available phones)
-if another phone was previously connected, the Gateway tries to reconnect to this one
first
If the pairing is not possible within 2-3 minutes, you can try the following steps
-Turn the radio OFF and Back ON after 20 minutes
-Turn the BT option OFF on your cellphone, reboot and try again
-Disconnect the Gateway Lite BT from the power and reconnect
-Search for available firmware updates on our website

C. There is no Text:
The iGateway is designed for vehicles with text display. It will not operate properly in non-text mode,
(although BMWs can operate in that mode too). The most important things to make sure of:
-Text mode is set ON by default –except on BMW
-ON BMW you need to set the text mode after product installation. There are 3 different
display modes (Radio, MID and Navigation) and each requires different configuration
-On iGateway you have full menu TEXT display, so the menu is displayed as text too. If there is
no text, it could mean that the iPod is in iPod UI (Simple remote) mode where the
communication is limited (‘iPod UI’ is displayed on the radio/cluster)
-In Audi if the text is not visible enter the text selector menu and set text function again
(Track02) –see next page for more information
-iPod/iPhone is not recognized properly (AUX GW)

To set text from the text selection menu:
1. Turn the Radio ON and select the Gateway (CD-Changer)
2. Disconnect all devices from the Gateway and wait until CD5 / Track99 is displayed on the radio
3. Keep the FF (Fast Forward) button pressed for at least 10 seconds, then release.
4. The display will show ‘Disc 1 / track 01’ within 3 seconds (indicating that you are in text
selection mode)
5. By pressing the Next track button, you can choose Tracks 02 through 04 which represent
different screen modes (e.g. MID, Radio). Please note: Track 01 is non-Text Mode
6. After choosing the mode you prefer, press FF (Fast Forward) to confirm and save the selection.
Or, by pressing the REW (Rewind) you can exit Text selector and discard changes.
7. If the text mode selection is correct ‘AUX GW’ will appear on the display
8. If the text selection was not successful, try again from step #3 and chose another option. Some
radios will work only with a specific track setting.
Please note: there is no text display at all if:
-If the cluster display is not compilant:
in Audi it does not display Tuner RDS info
VW Single CAN: The cluster display is not large MFA Highline
-In case of BMW, there will be no text display if:
Head unit is manufactured by Becker except 16:9 Navigation Radio (That
information is displayed on the label on tuner, there is no specification on the
radio to reveal it.)
The Head Unit is attached to a phone module or is prepared for one. This
issue can be encountered on the Business radio
if the customer does not know what he is doing . Sometimes on BMW there
is a separate button (‘M’ beside next track) for changing the button functions.
The customer simply forgets to press that button.
D. No sound on a BMW –only control
There might be 2 specific root causes to this issue:
-The car has a DSP unit installed
-The CD-Changer plug has not been connected correctly on GBL3BM1 (17-pin –also known
as Round-pin connector)
DSP: If the car has DSP, the device is not compatible, due to the design and architecture of the
Gateway. DSP systems require a digital input but the Gateway provides analogue output only, thus
there will be no sound, only control. The DSP unit is rare, and there is no indication of it on the radio.
Check the Tuner to tell: if there is coax connector on it, it is a DSP based system
CD-changer plug: The CD-Changer plug is a separate cable (comes with the 17 PIN plug) which ends in
a 10 pin white ‘molex’ connector. This connector can be connected 2 ways to the head unit’s CD-
Changer port. If the radio connects to the Gateway but there is no sound, it might indicate improper
installation. Rotate the white connector by 180°and plug it back in.

E. Factory phone sound is not audible (no sound)
The iGateway (GW100) uses the same harness as the Gateway Pro BT which has built-in phone function
as well. On that cable there is a separate 4-pin Molex cable. The wires on the 4-pin Molex are
responsible for the phone audio and mute.
On fig. 1 the 4pin Molex from the radio side quadlock connects to the 18pin Gateway side connector,
so the radio uses the Gateway Pro as a phone module. On fig. 2 the 4pin Molex from the radio side
quadlock connects to the car side quadlock connector, so the radio uses the original phone module (if
present). If the vehicle where the iGateway was installed, has a factory phone module, you need to
install the 4-pin Molex connector as shown on fig. 2.
Please note: This 4 pin molex is missing on Volkswagen Single Can Cable (GWxxVC1)
F. No sound from Navigation or phone (wires repopulation on BMW 17 PIN)
In some cases there is no sound when navigation/phone is used on a BMW with 17-pin (AKA round-
pin) connector. The root cause of this problem is the lack of certain wires (for sound) in the 10 pin
Molex (white) connector (Dension piece). In that case the wires have to be repined in the harness to
make it work properly.
G. Firmware update
Firmware update procedure on iGateway (former GW100) is complicated if compared to other
Gateway devices due to the lack of the USB port. An iPod has to be used to update it.
Please note: iPod touch or iPhone devices cannot be used to update

Update procedure:
-delete all previous update files and reset your iPod
-extract the downloaded ZIP archive
-copy the update package to the iPod using iTunes (approx. 750 files)
-disconnect iPod from PC
-turn the car radio on and change the source to Gateway (CD changer)
-select Music/Genres/_config/GW_Menu/Update/Start_Update and start playback on the iPod
-insert iPod into the cradle or dock cable –while it’s playing (the update process should start
automatically)
-After about 5 minutes the Gateway will restart with the new firmware
-When the starting screen appears on your iPod, you can check the version number in the top
right corner of the screen
Please note:
The update process works only in Gateway User Interface mode (the iPod buttons are locked and
control is possible from the head unit only).
Important note for Peugeot or Citroen users: Start the engine before perform a firmware update in
order to avoid ‘Economy mode” activation
H. BMW-specific issues (volume changing, CDC cannot be selected)
On BMW, it happens quite often that they forget to disconnect the original CD-Changer properly.
Please note: The installer needs to disconnect all cables physically at the CD-Changer (2 separate
wires), otherwise they will experience strange issues like:
-Volume changes automatically/randomly within 10-15 seconds
-CD-Changer source can or cannot be selected but even if you select it, you are back to
radio mode within 2-3 seconds
I. Activation on VW (Volkswagen CAN BAP –GW17V21)
The Media option is disabled on most CAN BAP based systems (VW –GW17V21), therefore it has to
be coded before or after the Gateway installation. The procedure is not difficult (takes 10 minutes
approx.), the vehicle needs to be taken to a service place and the ‘Media Player 3’option (2E) has to
be programmed using a service computer.

J. Volume is distorted or low compared to other sources
The iGateway has no USB port, so an iPod has to be used to change the output volume. Visit our
homepage, go to Knowledgebase and look for the volume configuration files in the Download section.
Volume setting procedure:
-connect the iPod to the Gateway, make sure you are in ‘iPod GW’(gateway) mode so that all
controls are available via the Head Unit
-disconnect your iPod and select the volume configuration file (0.5, 1, 2 or 4 –first two are
recommended upon distortion) and press play
-connect your iPod to the Gateway (you have 1 minute to start the procedure)
-the volume configuration procedure takes about 2 seconds, when finished, the next song will
be played
-turn the Audio System OFF, remove the ignition key and wait for 30 seconds, turn the Audio
System back ON
-Test your Audio System. If the volume output is still distorted, please repeat steps 2-5 with the
0.5 volume configuration file
Please note:
-the volume changing method above does not work with iPod touch or iPhone (!)
-if the problem persists, make sure that the ‘iPod GW’mode was active upon setting, if yes:
please use a different iPod and repeat the above steps
-these volume configuration files work on iGateway only
