2.7.1.
Audio-insertion
This interface is only able to insert video signals into the factory infotainment. If an AV-
source is connected, the audio insertion has to be done by the factory audio AUX input or an
FM-modulator. The inserted video-signal can be activated simultaneously to each audio-
mode of the factory infotainment. If 2 AV sources shall be connected to the infotainment,
additional electronic is necessary to switch the audio signals.
2.7.2.
After-market rear-view camera
Some vehicles have a different reverse gear code on the GM-Lan which the video-interface is
not compatible with. Therefore, there are two different ways of installation. If the video
interface receives a signal of the reverse gear, the green wire
“Reverse-OUT”
of the 20pin
cable should carry +12V while the reverse gear is engaged.
Note:
Do not forget to set video interface’s dip5 to ON before testing.
2.7.2.1.
Case 1: Interface receives the reverse gear signal
If the interface de12V on the green output wire of the 12pin interface cable while
reverse gear is engaged, the video interface will automatically switch to the rear-view
camera input
“V4 Reverse”
while the reverse gear is engaged.
Additionally, the +12V (max. 3A) power supply for the rear-view camera can be taken
from the green wire of the 12pin interface cable.
