Just did a little hunt for some units on eBay and noticed they are saying if factory unit is RCD300 or RCD500 then the canbus needs upgrading.
Upon more research it seems this involves replacing the factory canbus and then needing to do some vcds/vag com stuff. Daunting stuff to me. Anyone have any insight on this?
When it comes to installing head units I have done a few and it should be fine but this whole canbus vag com is a whole new language to me and daunting.
Edit: should also point out I believe I have the RCD500.
