Windows Phone 7 Bluetooth handsfree problem

My Samsung Focus is having problems working with my built-in handsfree bluetooth system in my car (Infiniti G35).  The phone discovers & pairs just fine.  However, any call connection results in horribly garbled audio.  I discovered that if I disconnect the BT connection from my car during a call and then reconnect, the audio recovers to work fine.  However, the next call will result in the same problem.  I drove over to the ATT store & tried out their display models, both another Focus & their HTC Surround.  They BOTH exhibited the same problem, so it appears to be a WP7 problem.  I did try my phone on an older model G35 w/ handfree BT which worked fine.  My old iPhone 3GS & other droids work fine w/my car.

Anyone else experiencing similar issues?  From my basic testing, it appears to be a MS software / driver problem.  Help!
