Hello all! Newbie here... I turn to you all because I have hit a brick wall. I (meaning my wife) own a 2011 C180 Kombi (German-spec) with comand setup and installed a Kenwood CMOS-210 reverse camera this past weekend. However, the comand does not show any video. Everything was installed/configured as per the many wonderful posts here but no luck.

More specifically, I installed the camera to the comand video input via the green FAKRA cable from eBay and powered it up using the cigarette lighter plug in the front console. That power source is never used and seemed cleaned using a multimeter. I checked the voltage at the camera and it is getting a solid 12V. I haven't tried connecting it to a chassis ground yet.

Then I configured the comand for reverse camera and, within the engineering menu, "aux video off" and "SVRC". The monitor goes to black when engaging reverse showing the typical message "check entire surroundings" and 'back" but no image.

At this point I assume the camera is working, the comand was configured properly, the FAKRA cable is good and everything is powered correctly. Am I missing something?

Please help!

 

You haven't connected what to chassis ground yet? You need 12 V + connected to camera (which you say you have), a ground wire connected from the camera to the chassis and the video cable. You can't rely on the shield of the video cable for power ground. To check the camera, get one of your old TVs and plug the RCA video jack from the camera into the yellow jack on the TV (analog video) With the TV on and the input selected and the car key on, you should see a picture.

 

Thanks for your reply! I meant that I connected the camera to the positive and negative wires to the cigarette lighter plug. Even though it is a steady 12V, maybe that was not a good place to connect it to.

 

I figured it out... My Euro-spec NGT4.5 has three green FAKRA inputs... a single input (aux video) and a double input connector. I had connected the reverse camera to the aux video input which was wrong. It needed to be connected to one of the double inputs (after removing th FAKRA housing) for it to work. Everything works perfectly now.

 

I got the same problem like yours! Read again and again all thread about this but no luck. Could you post some photos? Which one is correct input for rear camera? Thank you so much!

 

Lovew204 - take a look at the picture along the bottom of the radio. You will see an empty brown double connector (nothing connected on mine) and to the right is the double green connector. The first one (closer to you) is empty and is the one I used.

Let me know if this works... It took me two weekends to figure this out and should have taken more pictures. The installation was very simple (time consuming) and was surprised how easy it was to remove the radio thanks to posts on this forum.
