I'm having similar problems... I have the latest firmware from Palmone, but the car shows "activate phone" even after successfully pairing the car and phone. If I initiate a call from the treo, the car will pick it up, but incoming calls don't work. During the brief intervals the phone is "activated" during an outgoing call, the address book is unpopulated.

I also can't find "allow wakeup" in any option menu. I tried deleting all my favorites, and that just seemed to clean up the endless reboot issue.

I am really, really, frustrated!!
