I already have a 6 cd changer as standard in the boot of my Bora connected to my Gamma headunit.

I've seen an audi single DIN MP3 changer (6 disc). Will it work with my headunit when playing MP3s? I'm guessing its the changer that does the decoding and the headunit just outputs the sound (a very simplistic view).



The part numbers for this ^ disc Audi single DIN MP3 changer are

4E0 035 110 A

4E0 910 110 L

I'm guessing one is the hardware number and the other is software?
