Work in progress:
After looking around at RNS510 upgrades and DNS options, I must admit I'm an android geek and really want it in a 2 DIN solution.

So looking at this option due to the XDA community support:
Capacitive Pure Android 4 1 2DIN CAR Radio DVD Player 3G Wifi GPS Navigation FM | eBay

Looks like it would need a face plate adapter and maybe some other bits and pieces, no idea at all as I've just bought the Golf!!!!!

So if I go complete alternate head unit, what gear do I need to hook into the Canbus system etc - or is there a decent head unit already designed for VW without adapters and running decent spec?

Any info would be great guys.
Great forum.
