Thanks for that tip. It doesn't seem to make a difference, though. The pairing has always been easy and successful even with the old firmware. Both the phone and the car show the other device with the correct MAC addresses and such. THe car just doesn't recognize the phone until I initiate a call from the treo. Immediately after completing the call, it goes back to "activate phone".

How do you tell what rev your BT module in the car is?
