I'll start off by saying that i have a 2009 audi a3 black edition 8p3 with rnse.
A few years ago my dad had an Audi A4 (not sure what year unfortunatly) that came with factory cd changer, he got rid of the A4 a while back but kept the cd changer.
My question is will the cd changer out of the A4 work with my rnse in my A3?
i have the part number of the cd changer if that helps: 8E0 035 111
Im guessing its not possible due to firmware etc but it would be good if it will work as its a handy accessory to have.
