After-market rear -view camera
Some vehicles have a di
ff
erent reverse gear code on the GM-LAN which the included GM-
LAN box is not compa
ti
ble with. Therefore there is two di
ff
erent ways of installa
ti
on. If the
GM-LAN box can detect the reverse gear in the vehicle, the green wire of the 6pin to 8pin
cable should carry +12V while the reverse gear is engaged.
Note:
Do not forget to set dip5 of video-interface to ON before tes
ti
ng.
2.5.4.1.
Case 1: GM -LAN box detects reverse gear
If the CAN-bus interface de12V on the green wire of the 6pin to 8pin cable when
reverse gear is engaged, the video interface will automa
ti
cally be switched to the rear-view
camera input CAM while reverse gear is engaged.
Addi
ti
onally, the +12V (max. 500mA) power supply for the rear-view camera can be
taken from the green wire of the 6pin to 8pin cable.
