I just installed all wiring according to WIS, OEM Backup camera and modulator. I also programmed Comand with Star to enable rear view camera. However, I do not get video.

The Comand monitor are turned black in rear shift position and some very opaque lines are running from bottom to top of the screen. Not sure where to look. Any ideas what can be wrong. Is that possible to test camera and modulator with voltage tester to find out if they are in a good working condition.

I measured the power that is coming from pin 4 from left rear lamp (E3 e3) to modulator and it has circuit around 10-12V. I am not sure how to measure video output. How correctly check if the rear view camera sends video signal?

Many thanks in advance.

No, I have video input on pin 7 and 1 on Comand unit.

I just fix it. The wiring was incorrect. I swiped two wires and now it is working great!

No, I used OEM parts. It costed me much cheaper since I got them used.

vladc77, how did you program Comand with Star to enable rear view camera?

vladc77

it is a long explanation. In short, you need yo access your car and then make setting change in CGW (main module) and Comand modules with setting that back up camera is present.

Do you need a special computer or tool?
