I just upgraded from an iPhone 4 to a 4S. My Bluetooth functionality has worked perfectly fine with my my iP4 and 2011 Infinity M for both the phone and audio functionality for almost a year now. My new iP4S works fine with the phone functionality but thinks that it needs to reconnect when I try to play Bluetooth audio. My car says connecting to iPhone and my phone says connected. If I turn Bluetooth off on my phone and then back on again, the phone seems to continually toggle between connected and not connected. I connected the iPhone to the car as an audio device. I deleted all of the previous Bluetooth connections and added the phone back as the only device. Same thing. Phone works fine, Audio connection seems lost. Anyone else having any trouble with this?
