Just picked up a A4 B7, first thing I done was replace the tape player that was in it! Thought it would be a simple plug and play until I got no power and from reading on here realized its run by can-bus, and I would have to have a wire running from the head unit to fuse box!

My question is would something like this be a simple plug and play and actually work?

PAC CAN-BUS Adapter C2R Audi for Audi (Manufacture Year 2005-2010) as e.g. A4 (B7/8E), A4 (B8/ 8K), TT (8J), A3, etc. for all Aftermarket Radios Plug & Play: Amazon.co.uk: Car & Motorbike

Any other alternatives? Maybe a bit cheaper.. Haha

Thanks.
