Forget the Phatbox. Get an iPod and Dension's Ice-Link. Control the iPod from the head unit (and steering controls if your vehicle has them), PLUS you still get to see iPod display if you mount it near the driver. Dension have mounting solutions as well. Similar in principle to the Phatbox head unit link.

They'll be at Macworld next week in San Francisco. I'll see if I can get additional information that may not be on their web site.

The remaining question is obviously going to be one of compatibility. I don't know the extent to which Dension support the OEM head unit range. If they promote this solution well enough, I don't think it will take long for it to become the "standard" MP3 car installation.
