Wondering if anyone has had this occur, and/or if anyone has read about or discovered a solution.

CamHy non-nav, paired with cingular Razr - bluetooth works great with one exception that I discovered today.

I was on a very important call via bluetooth with my vehicle parked, and full signal bars lit on both the phone and non-nav display. A secondary call rang in on call waiting and I didn't push any buttons; just continued with the primary conversation. Unfortunately, when the second caller finally went to voicemail after the standard 4 rings, it disconnected the important call I was on and my stereo switched back to playing music. The phone readout displayed that the primary call was still connected, but I could neither hear nor be heard thru either the phone itself or via bluetooth.

Some background to eliminate the ever-possible "pilot error" factor:

- I am knowledgeable about pairing the phone, it has been paired for the 40 days I've owned the car, and I had bluetooth in my prior vehicle.

- Signal strength was rock solid at five bars and didn't budge at all during primary call or when the secondary call came in.

- I didn't push ANY buttons when the secondary call came in


Any thoughts?
