Got myself one of these, fitted in 30 mins with the help of guides on this site and gotta say very impressed.
Anyone who is thinking of spending 500+ on vw unit need to seriously consider one of these. iPod compatible etc etc, I spent £220 on a parrot kit (9200) and it is no where near one of these, in fact the parrot was rubbish in comparison!!!!
Just my 2p's for you!
Cheers
