BT Issues, multiple devices

[FortWorthMac]

Hello all,

Hoping someone here knows alot more about BT then I do.

I have a 2010 Jeep Wrangler that has built in BT speakerphone but not A2DP. I added this device

http://www.amazon.com/Blackberry-A2...1?ie=UTF8&s=electronics&qid=1265880346&sr=8-1

that basically adds A2DP to my system through my AUX port.

That then gives me 2 devices in use at one time, my speakerphone and the A2DP adapter. My iPhone 3G allows the use of both at the same time but the problem is after the music starts I get audio dropouts.

If I then unpair the car stereo the music plays flawlessly. But here is the kicker. If I then add the HF back both work great initially. If I get out of the car and come back then the problems start again.

Any idea what the problem is or might be?

Thanks
David
