What happens when you put the car into Reverse? Does the screen go black, with "Check Entire Surroundings" in the top corner?

 

Yes when I put the car in reverse the screen goes black with "Check Entire Surroundings" message.

 

Ok - I had a similar problem when i first installed my camera.

I know that you mentioned that you tested the camera on a monitor, but this may not be a reliable test for the COMAND unit.

I think it may be an issue with the rca cable/adaptor.

First try to toggle the AUX vid to off (which it should be) in the engineering menu.

If that works, then voila. If not, I would suggest running a camera test like I did.

1) take an old USB cable for a iPhone or something, and cut it. Cut it so you have wire tails that you can connect to the camera power (the ones that you would use when you are splicing it into the fuse box) and then use this new USB cable connected to the camera and plug it into the 12v power supply using a cigarette/usb charger.

From here, if your wiring is right, the camera should be powered (as long as the outlet is powered).

Then, take the camera rca cable and plug it into the FAKRA adaptor. In my case I had a long RCA extension connecting the 2 so i could run the camera to the back and use the rear fuse box for power. I found out that the extension cable was faulty.

At this point, you should be able to find the problem. Since you said that the camera worked on a monitor, if you deduce that it still works on a secondary monitor (bring it into the car and run the camera off the cigarette charger) with the direct rca, and your new makeshift power supply, then you know it is either an issue with the rca extension, FAKRA or the COMAND options.

Id swap them out - starting with the extension, then the FAKRA. It's common for the FAKRA adaptors to be faulty.

 

Thanks for the tips. I will give it a shot later on this week. We just had a Blizzard over here in the DC area.

 

Your problem seem just like the problem i had.

Tried to restart the comand????
Check PAL NTSC camera in Engineering menu???

 

I just had the same thing happen. I had the camera installed for a few weeks, no problems. This Monday morning camera worked fine. On the way home, stopped working. Back screen. I think the camera may have gotten burnt out since fuse #71 is cig-lighter and not rear light. I'm looking for a better solution to powering rear camera.

 

I was trying to look for the thread where you can use the back up camera in place of the license plate light. But still have both lights (left and right) working. I believe you have to use the LED type lights??? Does anybody know which ones to use and where to get them?

 

I have tried everything to get it to work - engineering menu on, COMAND menu on, switched out cameras, FAKRA'S, RCA'S, fuses, tried a reverse camera OBD II Activator - but reverse will just not trigger the damn screen!
I don't know what else to do..?

 

..anyone...please?

 

maybe it needs to have SCN code by the dealer

For me I went with command online and bought the original parts

Did the retro fit my self it was almost a straight forward after that I had to take my car to the dealer for the SCN code

I did enable the camera from the engineering menu as well asa had a black screen with check the surroundings I would recommend it better than playing with the fuse box

this was the link i used to purchase

 

Thanks.
I think that's the only thing left to do to let stealer strip some money off of me. LOL.

 

 

Could someone please post the items I need to purchase to completed this camera install or confirm what I’ve researched below:

I’ve read so many conflicting threads!

I’m wanting to fit an aftermarket kit. With the Sony CCD camera.

Car is: C63 AMG with NTG4.5

So my questions are:

1) For a U.K. car do I need a PAL or NTSC camera

2) Do I need a RCA extension lead?

I would really appreciate it

Do I need a RCA extension lead?

 

That's the camera I put in. I'm pretty sure I needed a lead, but it was years ago. Also you'll need a way to tap power and brake lights in the trunk. You can directly wire that or use one of those add a fuse extenders.

 

brilliant, thanks

Just ordered one for the fuse 71 in trunk
