Has anyone ever tried this?
I have 2 Blaupunkt CDC40 Operas, one of which seems to read CD titles (maybe it's just the music I listen to).

Assuming the hardware inside the CDC40 is the same maybe it's just a matter of updating the firmware to add MP3 support?

I'm willing to try it if someone can provide firmware from CDC40 + MP3 player...?
(Would be best to include dump of flash EEPROM too just in case, and security code of course)
