Hi Room,
My SD's original Becker radio has decided to stop working. I don't get a response from the on/off button anymore but the worse part is that the liquid display is messed up and I can't see if it is looking for a security code or just dead. I looked through my papers and don't find a radio code to enter..did these cars have them? I've checked the fuse and it's fine (all the other options that run from it work fine) and also wonder if there is a fuse inside the actual radio.

If someone can point me in the right direction before I pull apart the dash/console I would be grateful.

Thanks!
