This car radio is built for bluetooth phones and looks very cool for what it does. I'd love to see if they could make it stream music from a PDA via bluetooth. I've sent them an e-mail to inquire about such a device, but I'm not holding my breath. Wouldn't it be great to listen to all of the music locked into your Axim on your car stereo? I'd get alot of mileage out of that trick.
Looks like the only profiles supported are handsfree and headset, I'm not aware of any tools that would allow you to send music through these profiles. Even if you could, I doubt it would be in stereo.
