Maybe someone will try before me but here is the idea. Not having a more universal DMP connector solution really torques me off. However I found this little gem:

It plugs into the dock interface of any iPod compatible dock. With it it connects to any bluetooth device that supports the A2DP and AVRCP bluetooth profiles....like my Treo 750.
The idea here is to be able to keep my phone in my pocket and play through a playlist of songs via bluetooth.
I suspect that no song titles or library info will be displayed on the car display, which is fine.
If anyone gets around to trying this before me let me know your results. I think you can pick the device up at Best Buy. I'm kicking myself for not getting one when they were clearing them out at CompUSA going out of business sale.
