Hello everyone! I'd like to know whats the differences between preface/facelift interior? i want to swap the RNS-D in my car(2000) to some aftermarket unit, but there is a lot of version, and there is no conjuction between the years. for example:
https://www.ebay.com/itm/Audi-A6-C5-...wiU:rk:15:pf:0

or

https://www.ebay.com/itm/Audi-A6-C5-...LOOc:rk:2:pf:0
https://www.ebay.com/itm/Car-Radio-S...dQs:rk:19:pf:0
https://www.ebay.com/itm/Doppel-2-DI...J82:rk:20:pf:0

once its from 2000, another says 2001, and another says 2002.

I really use some help, cause i need to change this unit to something that is working properly or i'll go mad in my car!


thanks in advance!
