Beware of the hot airflow from your vehicle’s climate control system. We recommend securing the
interface to a suitable location that is free of sharp metal edges using double-sided tape, Velcro, or wire
ties.
The iPod/iPhone has not been designed to withstand extreme automotive temperatures. You may
damage your iPod/iPhone if you leave it inside your vehicle on a very hot or very cold day. For further

1.6 Important Compatibility Notes
If your vehicle is equipped with an external factory CD changer, you must disconnect it in order to be able
to install the interface. You will lose the use of the external CD changer to gain the use of your iPod,
Bluetooth or MP3 player. Any built-in CD changers will remain working.

Chapter 2 – General Installation
2.1 Installation location:
Most installations will require you to remove the factory radio in order to plug in the vehicle-specific
harness. For some vehicles, you will also have the option of connecting the interface to the factory pre-
run CD changer cable located in the trunk or glove box.
2.2 Tools needed:
In many cases, no special tools are required to remove the stereo. For some stereos, it is better to use
car stereo removal tools. Please consult your local car audio shop or your vehicle’s dealership for
instructions or assistance as necessary.
2.3 Preparation and adapter installation
1. Turn off car engine and remove key from ignition
2. If your radio uses a Security Code, make sure that you have the code before unplugging the
radio.
3. Un-mount your radio from the dash in order to gain access to the back side of the radio. Some
vehicles require special tools to remove the radio. Please consult your vehicle’s dealership or a
local car audio professional as necessary.
4. Attach the car harness connector to the back of the stereo via the CD changer port. Connect it
firmly without forcing it. Connect the other end to the interface
5. VW / AUDI / Seat / Skoda : there is a single black cable on the vehicle specific harness (3)
you will need to attach it to the metal part of the car stereo chassis The failure to attach the black
cable to the chassis of the stereo will mean that the GROM adapter will not work!
Remove the PVC from the end of the black wire (2)

(a) Connect the end of the black wire (2) to the metal part of the car stereo chassis. You can
connect it under the bolt (3) if present
(b) Make sure solid contact is maintained between the striped black wire and the metal part of
the car stereo body.
6. For AUDI vehicles only: For some AUDI headunits an additional part or harness modification is
required in order to gain the access to the CD changer port. The 8-pin CD changer port on such
stereos is occupied by a solid 20-pin connector. Please refer to the instructions at:
http://gromaudio.com/pie-audi-how-to.html or obtain GROM part # AUDS.
7. For BMW vehicles only: Please refer to the installation insert for the special guidelines for BMW
installation.
8. For Toyota/Honda vehicles only:
In some Toyota/Lexus/Scion and Honda/Acura vehicles the CD changer port is occupied with a
factory harness (such as NAV or audio harness). The GROM package for Toyota/Lexus or
Honda/Acura includes a Y shaped vehicle cable. In order to connect the interfaces properly
please follow to the scheme below.
If the car has no NAV or XM leave the female end of the Toyota or Honda (HON1) harness open.
9. Once the interface is connected to the radio, you will need to test the operation of the interface
before re-assembling the dash.
10. Turn your car stereo on and switch it to CD Changer mode using the Disc / Mode / CD / AUX
buttons (depending on the stereo type) on your car stereo until it shows Disc 1, Track 01 on the
display.
11. Connect the iPod cable to the iPod. Turn on the iPod. You should now hear the sound coming
from the car stereo speakers.
Once the operation of the interface is confirmed, you may continue with the installation. If you
experience difficulties with the installation, please see our troubleshooting section.
12. Find a place where you can place the GROM. In many cars there is enough room inside the
dashboard to place GROM.
Note: Make sure you mount the GROM in a place with enough room so that, when you re-mount
the car stereo, you do not break the adapter.
13. You may use the glove box or other spaces on the dash to direct the audio cables out.

14. Re-mount your car stereo, making sure its clips or screws are secure.
Adapter mounting in the trunk
(for VW and BMW only)
1. Locate the trunk mounting cable in your car (usually located along the left side of the car in the
back).
2. Disconnect the existing CD changer, if present.
3. Attach the matching cables
Note for BMW trunk installation:
Some BMW’s are factory wired for a cellular phone. Except for wire location, the factory cellular phone
connector looks identical to the factory 3-pin connector used for the CD changer. The CORRECT 3-pin
connector for the CD changer has a BROWN wire (ground) in the #1 pin position. Please make
certain you use this connector.
The INCORRECT factory cellular phone connector has a BROWN wire in the center position—DO NOT
USE THIS CONNECTOR.
Congratulations! You have installed the GROM iPod adapter. You may now use it with your
iPod/iPhone.

3.2 Basic features
The GROM-iPod adapter has two modes of operation:
3.2.1 Simple mode:
iPod stays unlocked. Your iPod can be controlled via its clickwheel or via car stereo controls. The
information displayed on your car stereo does not represent the actual song position on the iPod (the
song’s number). There is no need to prepare your iPod to play in this mode. The simple mode is always
selectable by choosing CD1 (DISC1) from the car stereo. To switch to advanced mode, just select any
disk other than 1. Please refer to the section 3.3 of this manual for the description of the supported
operations in the Simple Mode.
3.2.2 Advanced mode:
Your iPod is locked for control and only operated via car stereo buttons. In this mode all data is synched
between the stereo and iPod which allows you to see current information such as track time, number and
playlist (disc) number. Text is also available for certain stereos. In order to use this mode you have to
prepare your iPod as explained below.
The advanced mode is always on for disks 2-9. To switch to simple mode just select DISC 1
“Ok to disconnect” is shown on the iPod display while it is connected to this unit. The clickwheel of the
iPod is disabled when in this mode.

the current track.
-Disk Change
When changing the disk other than 1 the iPod will switch to the Advanced Mode
None of the information displayed during the simple mode is related to the song currently playing. The
display will show: DISC 1 TRACK xx TIME 00:00. Track information can change from 00-99.
3.4 Supported operations in Advanced Mode
In advanced mode iPod controls will be locked and the following operations will be supported:
-Next track
When pressed on car stereo, iPod will jump to the next song and car stereo track number will
represent song number in a current playlist
-Previous track
When pressed on car stereo, iPod will jump to the previous song and car stereo track number will
represent song number in a current playlist

-Scan
Allow to skip tracks by 10 when set. Next track will jump to current track+10. Previous track will
jump to current track-10. It is helpful to skip the whole album (usually ~10 songs)
-Disk Change
When you select Disk 2-9, iPod will stay in Advanced Mode and will resume last playing track in a
playlist. Once DISK 1 is selected, iPod will switch over to Simple Mode
-Mix/Random
When turned on it will allow playing songs in a shuffle mode through the whole playlist. The track
enumeration will start from 1. When switched off, track enumeration will be restored to the real
order in the playlist.
-Repeat
When turned on, will play first track in the playlist after the last track is played.
The display will show disk number, track number and track time of the currently playing track.
3.5 Playlists set up for advanced mode
To use your iPod in Advanced Mode you have to define playlists. The number of playlists depends
on the stereo (usually 5-8). We recommend naming the playlists starting with the number according to the
desirable disc position.
1-Andy’s songs
2-Disco dance
3-Favorites
4-House rhythms
5-Smooth Jazz
“1-Andy’s songs” will be mapped to Disc 2; “2-Disco dance” will be mapped to DISC 3, and so on.
Therefore selecting DISC 2 on car stereo will play “1-Andy’s songs” playlist; DISC 3 will select “3-Disco
songs” and so on.
Note: For stereos with disc ^ and disc
V
you may set up to 10 playlists, on some stereos up to 99.
We strongly recommend that you organize your songs into playlists and enumerate them for proper
operation of this unit.
If your iPod does not have playlists/songs it may cause unpredictable outcomes and improper
operation of the unit.
EMPTY PLAYLISTS MAY ALSO CAUSE UNPREDICTABLE BEHAVIOURS, ESPECIALLY EMPTY
PLAYLISTS THAT ARE LOCATED IN THE MIDDLE OF ALL OTHER PLAYLISTS.
Note for iPhone users: Once connected to the GROM adapter, your iPhone will register a message
stating “This accessory is not made to work with iPhone.” It will ask if you want to “Turn ON the Airplane
Mode.” Please answer “NO”. If the stereo still does not recognize the iPhone, please restart the iPhone
3.6 When the car ignition is OFF
When you turn your car stereo or car ignition off, the iPod will automatically will go into sleep mode. In the
sleep mode, the iPod will still consume power—although very little—from the car battery. There is no
need to disconnect the iPod every time you turn off your car.

rev. 4.1 Copyright©GROM Audio, 2011

However, it is strongly advised that you disconnect the iPod if you do not plan to operate your car
for 1 week or more.
3.7 Using EXT for AUX-IN on your GROM-IPD3 adapter
You can connect any alternative audio sources such as MP3 player, DVD, GPS, XM and etc. to the
GROM IPD V3 adapter via GROM to RCA and 3.5mm phone jack cable (must be purchased separately,
is not included in the basic package). Connect MiniDin end of the GROM RCA and 3.5mm cable to the
GROM adapter. Connect 3.5mm end to the audio source. Turn ON the audio source and the stereo. Put
stereo into CD changer mode. The music will start playing. We recommend that you unplug the
iPod/iPhone from the dock connector if you are using the AUX-IN RCA 3.5mm cable on GROM-iPD3
adapter. If you don’t unplug the iPod/iPhone and connect the 3.5mm audio source at the same time some
sound interference may occur.
3.8 Using EXT for Bluetooth connection on your GROM-IPD3 adapter
You may connect the GROM Bluetooth Dongle to the EXT port on the GROM-IPD3 adapter for the hands
free use of your mobile phone and wireless music play. Please refer to the GROM Bluetooth Dongle
