Hi, I have an 04 S430, and the radio and navigation system completely quit working. It does have power, but nothing works on it. Any suggestions other than pay dealer several thousand for a replacement unit?

 

is there any sound coming out ?

 

I have the same problem,please help.

 

Last year a lister informed us that MB had extended the warrany ( unlimiited time if I remember right) on the dash displays and such. I would check to see if this radio/navigation problem is covered under that little knownwarranty. Someone might know off-hand or someone may have a copy of the warranty that was spread among listers.

the recall covers the cluster for 10 years and 100k miles or unlimited miles...ill. check on monday....it has nothing to do with the sound system...for your 2004 it could be a few things...may need new software update for the comand unit in the dash...
does the audo power up? do you get a display? if you have a display and just no sound it is one of the modules in the d2b ring which is usally the sound system amp in the l/r trunk area or the psefor the phone? please give some more info
