Sounds attractive, except my damn car doesn't have an AUX in. Yes, it has an iPod (not iPhone) input, and it has Bluetooth (but not A2DP), and no aux jack. I could maybe tear out the iPod interface and find a simple AUX jack (which, like the iPod adapter, would pretend to be a CD changer), and *then* have *another* box to convert that aux jack to A2DP.

This seems like a recipe for pain.
