2.6.4.

 

After-market rear-view camera 

 

Some vehicles have a different reverse gear code on the CAN-bus which the included CAN-
box is not compatible with. Therefore there is two different ways of installation. If the CAN-
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 testing. 

 
 

2.6.4.1.

 

Case 1: CAN-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 automatically be switched to the rear-view 
camera input CAM while reverse gear is engaged. 

 

 

 

Additionally, the +12V (max. 500mA) power supply for the rear-view camera can be 
taken from the green wire of the 6pin to 8pin cable.
