So you said. But I'm sure there is a factory reset for the whole stereo like there is on most electronic equipment. All I found on Google was a workshop manual for a very similar looking Fiat/Blaupunkt unit but the factory reset procedure didn't work on mine.
I think you're misunderstanding what I'm looking for. I appreciate the method described in the manual doesn't work to delete the CD names. I'm trying to find out what sequence of button pushes will reset the radio to it's factory default status i.e. no radio stations stored, no CD names, no user EQ settings etc. I had a search a while back and the Blaupunkt workshop manuals I found all listed factory reset procedures, just not ones that worked with my particular stereo. I'm sure someone outside of Blaupunkt knows what the sequence is.
