W205 audio 20 "no signal"

[martinspeight]

I have 2015 C200. Audio 20 system has been fine until recently but now it won't start. Navi, radio, media all state "no signal". Reversing camera` mostly fails to operate, but occasionally springs to life briefly. Any ideas about system resets, new software, general advice would be much appreciated.

Sounds like an electronic issue, maybe loose wiring or fuse. I have an estate c220 2016 but that has a fuse box located in the boot compartment. Possibly check there for any blown fuses first?

Thanks, I'll investigate the fuses (when I discover where they are!).

Further symptoms : the system constantly loops through a) 2 seconds Mercedes logo, b) 10 seconds warning about being distracted by the system, c) circa 30 seconds "no signal" printed in coarse white letters on black screen, then back to a) endlessly. Reset buttons make no difference. Reversing camera only functions in sections a) and b), not in c). Feels like a computer stuck on a boot cycle.....

Hi Martin,

Do you (hopefully!) have found any solution to your issue?
I'm having the exact same problem and can't find anything useful on the internet that helps solving it.
It also happened out of nowhere to me. Just after a stop at a service station I saw the rearcamera was not working (the no signal message)

Anyway, hope you have found some luck in the solution?
Looking forward to hear from you, or anybody else who knows more about this.


Kind regards,
Casper
