My W220 has a haunted car radio
I have a problem on a 2002 W220 320 CDI with the car radio (pre-facelift, small screen) i'm unable to change station on the car radio. When I change the station, the radio immediately returns to the station maybe defined (by the previous owner?). So I have to turn off this "haunted" car radio.
When I turn the radio back on, it is still on that same radio station. I don't understand it.
Would you know if this is due to a setting or if it is a glitch? Is there any way to reset the car radio?
Thanks.


Does every radio preset give the same station?
What does SEARCH do?
What does AM do?
