My 2004 mercedes-benz s500 radio turns on then says system unavailable and shuts off. I've tried to reset it to no avail
post all things that fail and work both
all maters
engine starts , runs , drives ok ,day or night?
all other electrical things on the car ,as in ALL do in fact work correctly?
or just the RADIO on the car fails.
many cars now the RADIO is part of the CAN , the car Area Network. and if that fails so does the RADIO.
if is in fact a factory RADIO there from MB.
what to do.
well
check all fuses first. never skip the easy first step and a 50cent cure..
next scan the USA? OBD2 scan port, and look for Radio errors
like COMM failures codes.
can I assume this RADIO is not SDAR , satelite radio
if is did you path the subscription bills? $$$$$$
or
the RD is base Radio and both are in fact CAN bus controlled
so yes, it must be scanned first, after fuses
sorry this is no simple 80s radio, not at all
and is antitheft protected too.
i request this post be moved to cars and not computers.
here is more than 1 fuse, the RD shows 2, F1 and F2
my online docs, are not so good, on all MB.
get the car scanned in any shop.
see the DTC error codes. next.
