v.nice New VW Bus concept comes with iPad interface
and I can imagine Apple doing a better job of upgrades than VW/Continental currently do with their RNS510.

I can imagine a suite of VW apps where you could purchase an app to dial up boast for a weekend of fun and then it returns to stock. All for $9.99AUD.

I can imaging a better UI than the less than optimal RNS510.

Set your music and navigation options from home, plug it into your car, and off you go. Arrive at your destination, unplug your iPad and read your favourite eBook.

Bring it on VW.
