Just out of interest as this is on my list of things to do (when I get a car) how much was the head unit and associated kit, where did you get it from and how long did it take to install. Cheers
Hey mate...
I paid :
£440 for a mint RNS510 (version P) LED unit which included antenna
£3 for trim removal tools
£6 for aerial adaptor
You might also need a new CAN gateway depending on the year of your car. Mine is an 07 so didn't need one. Pre 07 needs one to avoid battery drain.
Took me about an hour to install. Took me longer than it should have cos I was being overly cautious with the trim as I didnt want to snap any tabs prying it off.
I have yet to get my unit coded in with VCDS though.
