Found this great AirClick hack on TuneVroom site!

Also, saw some new and improved mounting ideas for iPods (ie. in ashtray) at TuneVroom, but nothing for Acura. Not sure the (BMW) ashtray mount would hold an iPod safely in place.

I stopped into an "iPod2Car" stereo shop today, but their Peripheral unit wasn't chart-compatible, w/navi. They had a cool-looking Eclipse A/V/navi unit with iPod integration. Looks like price started at $2K....
