reverse camera not working
I just purchased a 2008 S550 and the reverse camera is not working. Here are the symptoms
When I select the reverse gear, nothing is changing in the screen, no "check your surrounding", black screen or blue screen.
I checked the codes and there is no communication with the rfk module.
I checked the power and ground at the module and it's good. I also checked the signal coming from the reverse light and it is also good.
The 4 wires were cut at the left trunk hinge area, I soldered all of them but still no change.
I read that I should be able to turn the reverse camera on from the cluster in the assist area but it doesn't show that option.
I have the xentry unit so If you have an idea on how to fix it please let me know.
I forgot to mentioned that in the command screen, I don't have the video option at the top.
Thanks

in the cluster menu - you can chose IF you want it to come on when reverse gear is selected
if its a pikey aftermarket fitment, it might explain why there is no menu (to have it auto switch on), and why there is no diagnostic info
in the hidden dealer cluster coding choices is the option to select if the menu to chose if you want it on or not is displayed in the cluster - start there?
the wires snap on the harness to the boot lid and it stops working - its a design feature Mercedes build in to the cars...

Thanks, I will look into it.
I decoded the vin and it came from the factory with option 218 REAR-VIEW CAMERA.

I was able to get the message in the cluster that enable or disable the reverse camera but still no change in the command display
when I put it in reverse.

That make sense but if it was the case, shouldn't I see the screen change from let say radio to a black screen with the check the surrounding note?
Thanks

enable the feature in one menu, then find similar again three more times with slightly different wording
Aktuelle Menueinstellungen Default - KI variant Settings
Rückfahrkamera - vorhanden
Also where you want to
turn OFF second to last - Reiserechneranzeige bei 50% Reserve mit Symbol - Less than 50% remaining after low fuel light Show Red pump symbol - turn this crap OFF
and turn ON last - Tankinformation deaktiv - turn this ON
then camera turns up again in
KI menu activation
Aktivierung Rückfahrkamera automatisch mit R-Gang
and again in
KI dealer level - Cluster user config
Aktivierung Rückfahrkamera Speicher 1 automatisch bei R-Gang
and again in
KI factory level - Cluster user config
Aktivierung Rückfahrkamera automatisch bei R-Gang

Resolved?
Hey ever get this resolved? I bought my s550 with a blank display screen. Replaced COMAND with exact model and the display now works. BUT there is no video tab and the backup camera is non existent. The car is equipped with a camera. Have you been able to figure this out?
