Navigation/radio Comand APS NTG1 and NTG2 navigation system
Limitations
Video only The interface inserts ONLY video into the infotainment,
for sound use the FM-modulator, the AUX-In interface AUX-110 or factory AUX
which can be coded by dealership.
Video-sources The video-inputs of the VL2 are compatible with NTSC sources only. But if a
factory TV-tuner is installed, it is possible that only PAL sources can be
connected.
1.2. Checking the compatibility of vehicle and accessories
1.3. Dip-switch settings
With the video interface boxes dip-switches it is possible to dis- or enable the interfaces
inputs (dip 1 to 3) and to preselect the type of camera which is
(to be) installed (dip 5).
Dip position down is ON and position up is OFF.
1.3.1. Enabling the interface’s video inputs (dip 1-3)
Only the enabled video inputs can be accessed when switching through the video sources. It
is recommended to enable only the required inputs for the disabled will be skipped when
switching through the video interfaces inputs.

1.3.2. Rear-view camera settings (dip 5)
Depending on whether no camera, after-market camera or
factory camera shall be used, dip 5 must use different settings.
If set to OFF, the interface switches to factory picture when the
reverse gear is engaged to display factory rear-view camera or
factory PDC picture.
2. Installation
Switch off ignition and disconnect the vehicle’s battery! The interface needs a permanent
12V source. If according to factory rules disconnecting the battery is to be avoided, it is
usually sufficient to put the vehicle is sleep-mode. In case the sleep-mode does not show
success, disconnect the battery with a resistor lead.
If power source is not taken directly from the battery, the connection has to be checked
for being start-up proven and permanent.
2.1. Installationsort
The interface is installed on the backside of the monitor panel. Therefore, the head-unit
must be removed.
Remove head-unit.
Remove the upper cover including the DVD/
navigation device. The external daughter PCB
is plugged in between the flex cable of the
monitor panel and the mainboard of the head-unit.

2.2. Connecting the flex cables
A rotated and a normal 30pin flex cable are included in delivery. Depending on the
orientation of the flex cable connectors at the monitor panel and at the mainboard the
rotated or the normal flex cable have to be installed.
Connect the flex cable from the mainboard to J_IN of the external daughter PCB and the flex
cable from the monitor panel to J_OUT of the external daughter PCB.
Electrical the contacts have to be transmitted similar, in other words the left contact of the
monitor panel have to be connected with the left contact of the mainboard. Please take note
of the contact surfaces of the flex cables during installation.
Note: Depending on the very navigation head-unit, the original flex cable needs to be
changed into a flex cable of the package contents. In this case, with the original flex cable
installed, the inserted picture will be scramble as if synchronization was missing.

2.4. Installation procedure –function check
Follow the below procedure using the “Connections” scheme from chapter 2.2. as reference.
Before the installation of the sources and the interface we recommend a first quick
connection of the interface and test run to ensure that vehicle and product are compatible.
Due to changes in production of the vehicle manufacturer there is always the possibility of
incompatibility.
-Switch off ignition and disconnect vehicle’s battery
-Remove vehicle monitor and open the body as described in chapter 2.1.
-Remove vehicle flex cable from the flex cable socket of the mainboard
-Plug in external daughter PCB between flex cable of the vehicle and flex cable socket
of the mainboard (see chapter 2.2.)
-Connect external daughter PCB to the video interface
-Connect female 6pin connector of the 4pin cable to the video interface
-Connect 4pin cable to the pins of the Quadlock as shown in chapter 2.3.
-Plug keypad into “Switch” connector. Even if the keypad shall not be used, its
installation (e.g. in a hidden spot) is recommended for support reasons
-If audio insertion shall be used, connect it according to chapter 2.6.
-If 2 audio sources shall be used, connect it according to chapter 2.7.
-Reconnect battery and turn on ignition
-Check LEDs on video interface, one each must be on
-Try to activate video sources by keypad (see chapter 3.1.), using a test picture source
-If camera is (to be) connected try to engage reverse gear with test picture source
connected
-If 2 audio sources shall be used, connect the audio wires and check the audio
function
-ONLY after positive function check proceed with final installation of the video
sources!
-After installation and connection of the real video source(s), adjust picture settings
(see chapter 2.5.)

2.5. Picture settings
The VL2-MBN2 does not have an OSD like other VL2-xxx interfaces. After installing the
sources the picture settings can be changed using a pen on the 3 buttons of the video
interface. The buttons are embedded in the housing to avoid accidental changes during or
after installation. Press UP or DOWN to change the brightness. To change the contrast, press
UP or DOWN while holding the MENU button pressed simultaneously. UP or DOWN must be
pressed repeatedly to change values, do not longpress.
2.6. Audio insertion
This interface can only insert video into the factory infotainment. The video can be activated
to any audio mode of the factory infotainment. If an AV-source is to be connected, the
source’s video out is connected to the video IN1 of the video interface and the source’s
audio out to the audio insertion. Audio insertion is possible by factory audio AUX input, the
optional available AUX-In interface AUX-110 or FM-modulator. The factory audio AUX can be
coded by the dealership.
2.7. Connecting 2 AV-sources
If two AV-sources shall be connected, connect the included audio cable to audio-switch-port
of the video interface. When switching the video interface from video-IN1 to video-IN2, the
audio will also automatically be switched.

3. Interface operation
3.1. By keypad and steering-wheel
The keypad can be used to execute interface functions. Each press will switch to the next
enabled input. If all inputs are enabled the order is:
Factory video  RGB-in  video IN1  video IN2  factory video  …
Inputs which are not enabled are skipped. If the audio cable is connected, when switching
from video IN1 to video IN2, also the sound will be switched.
