I'm with Tony. In the modern world, particularly for new cars, there's no opportunity for installing a third-party stereo. You get whatever the manufacturer lets you get, unless you're willing to endure a very high pain threshold to reengineer your dashboard.

What kills me is that, while it's entirely technically possible to wrap a very slick interface around an iPod, most manufacturer-sold car iPod integration kits are really kludges. Consider, for example, the Audi A3. The integration kit basically emulates a six-CD changer, placing your first five placelists on the first five disks, with everything else on the sixth. No search. No decent organization. Lame.

For most other vendors, iPod itegration is nothing more than a mini-phono jack. Be still my beating heart.

I wonder if part of the problem is the unwillingness of car manufacturers to tie themselves more closely to Apple. If there were a sophisticated industry standard protocol spoken by all DAPs over standard USB cabling, you'd think the car manufacturers would be all over it as a standard checkbox. Bluetooth A2DP is almost there as well. But show me a car that supports A2DP.
