Theres a few options:
One is the dealer fit Touch kit, this gives you a small screen looks kinda sat nav-ish, that attaches to a bracket.
Theres the Fiscon and MoBridge options, which are quite close to factory fit, and they allow use of iPhone and Blackberry.
Theres VW`s own factory fit, but if you order this with your car, you will be limited to rSAP phones - i.e. not iPhone or BB.
Then theres the kit I have, but not fitted yet, which is original VW kit like they would fit at the factory, but isnt tied to rSAP phones only. Got mine off ebay a few weeks ago.
Hope that helps some...
