My car is a Mercedes C250 CDI, 2012. 

Few weeks ago my my Navigation stopped working. It displays "No Navigation" message on display

Also i have No sound on speakers, though it finds radio stations on display.

I used Star tester and it showed me "telematic control module" fault permanently.

I don't know the location of this module.

Does anyone know where is located? 

I checked the trunk, but there i found only the amplifier, where can it bee that module.

Best regards,


No, I didn't find the module in trunk

In trunk I have the sound amplifier, fuse box and an antena spliter... nothing else.

I'm thinking maybe it's in front console, behind display

Next week I hope i go to Mercedes dealer to diagnose again and maybe they'll tell me how to find that module.

At the Mercedes dealer they told me that they can't access the multimedia command unit with the diagnostic tool ... and they recommended to repair it.

So my central multimedia unit, for now, is at a guy who repairs electronics.

Next days i'll find if it could be repaired.

I think the module is inside command unit.

Only the amplifier is a  separate module, but it works.

Yes please. Where is the location of Telematics control Module???  can't find it...

Searched on google, still didn't find anything.
