I changed mine to the MP3 version (2 din) but I couldn't stop it from skipping, tried different type of discs and write speeds. In the end I changed it back
Also where the old one would switch off with the ignition the MP3 one I had to physically switch it off, worried in case I forgot and came back to a dead car
If anyone wants a 2 din MP3 for a panda, let me know, collect from Sheffield or postage at cost
