iphone bluetooth interference garble with Pioneer DEH-P7000BT car stereo

Thank God I'm not crazy! I have the identical problem same stereo in car, same garbled speech on bothends of the conversation. You didn't mention it, but mine is cyclical - comes in about every 45 seconds or so, lasts from 10-25 seconds, then clear again. The connection with my first gen iPhone was crystal clear - a joy to use.

I spent an hour at my local Genius bar this weekend and am no closer to a solution, even after they swapped me for a refurbished phone. If anything it's worst. My best? Apple will have to first acknowledge there's a problem (no go on that yet) then fix it with a software update and who knows how long that will take. I

FYI I alsoemailed Pioneer to see if there is any firmware updates for the deck. I' e certainly not seen any on their site, but other than a confirmation email I haven't heard back.
