That's what I meant from my earlier post. Yes, BMW said that they corraborated with Apple with the BT. It was mostly done on BT specs not on actual testing. Think about this. Before the 1st batch of Iphones were produced for AT&T to test, the E70's were already out there so the actual testing was never done. They made sure that the BT module in the car would pair with the phone based on the specs but the actual call quality was not tested and guaranteed. Same thing applies for any brand phone and bluetooth headset. Unless you have the same brand phone and BT headset, the call quality is hit and miss. I went through about a dozen BT headsets before I can find the right one for my phone. To be honest, I don't think the software upgrade will even make a difference but who knows, maybe it will work perfectly when you get your E70 just like a few others out there. For me, I'm happy with my $99 dollar Plantronics BT headset with Audio IQ enhanced sound. Works and sounds better than pairing with any car BT module. Good luck!
