Does anyone have this problem? My new car supports Bluetooth hands-free calling. However, when I use it for Facetime audio, it sounds like an AM radio, and the person I'm talking to hears me like an AM radio as well. Hell, it sounded loads better on my old car using a cassette tape adapter through the headphone jack on the phone! It's almost as if the phone is switching to a really low quality codec for voice calls. Music over bluetooth sounds great. What's the deal?
