Radio will not turn on 2010 C300 4Matic
I had a 2010 C300 4Matic that was in the garage for 2 years without being turned on at all. Went to the mechanic, got a new battery, changed all fluids and its good to go except the radio will not turn on. I checked fuse 26 and 84 and replaced them anyways and still no luck. Any tips?
Also checked the fuse behind the head unit.

I guess Plutoe means measure the voltage supply from the radio connector to be sure wiring is fine.
EDIT: is the display dead? Checked fuse #11 too?
