theres a sony CDX A15 changer on ebay,will it be compatible with my mk3 headunit???
Lots of changers are compatible, but their connectors aren't compatible. It is a complete rip off IMHO, you need to buy an adapter for $$$$$$$$$$$s, when there is absolutely no need for it (you just have to know which wire goes where). For example i'm using a leon/audi changer in my ibiza with no adapter at all.
