I've done a search and can't find the answer to this one..... radio, '91 300SE, display flashes back and forth between the station set and what I think is a fault code "IC E". Since this has started, more often than not, all of the buttons are locked and useless, no volume control, no changing stations, and when playing a tape it acts like it is about to eject the tape then starts to play again. It still sounds good when I can momentarily get it to work right. Anyone else have this happen?

Hi, I have a similar problem. It started about a week ago... I use a tape adapter in my becker head unit in my '95 E320 W124. Now when I turn the car on, almost always the radio display starts flashing (but I don't see an error code), and the tape deck starts clicking like it's switching tracks on the tape adapter, but just clicks over and over... if i press a power window button it will start working for a few seconds... eventually it will usually start working (after driving a while, up to an hour at one point). When the car's off the radio works just fine.

Have you found anything out about what's causing your problem?
