My Mercedes 2011 S550 radio, navigation, back camera screen

Customer Question

Hi Michael,
My Mercedes 2011 S550 radio, navigation, back camera screen is off and does not turn on. It was working just fine yesterday and I did not touch anything. What should be the problem. I disconnected the battery and did not do anything.

Hi my name is ***** ***** I will be happy to assist with this today.

In some cases the battery needs disconnected for around 5 minutes to reset the radio/head unit or command unit as it is called.If this does not work usually it is the command unit needing replaced to correct this fault here.I have seen some of these fail requiring replacement for this issue here.This will need tested to be sure.

Let me know if you need anything else and feel free to rate my help here.

Thanks Pete
