My Acura TL has a Bluetooth phone interface made by Johnson Controls. With my Palm-based Treo, the phone would attempt to route a call to the car, but would fail and revert the call back to the handset. The second call would work fine with the car. I would generally just place a call to my voicemail, hang-up, and the next call would work fine.

With the PPC-6700, it always tries to route a call to the car, fails, and then allows me to select "Turn Hands-free On" manually to get it to work. Unfortunately, it requires me selecting it for every call, rather than just having a problem with the first call like my Treo did.

I suspect that the problem is related timing of how the Bluetooth interface operates when trying to connect to the car. Does anyone know what registry keys affect the Bluetooth headset timing?

Another workaround would be to have a "Turn Hands-free On" button on the dialer screen. Does anyone know how to accomplish this? I would be happy to buy a third-party dialer if it would offer this feature.
