I stated in a prior Bluetooth forum that I am having issues with the iphone 5 for AT&T with my xts platinum. Incoming calls go directly to the handset whether you press the talk button or select answer call from the screen. Answering another call from the cue screen while on another call results in the call being dropped. Finally. when you make a call from the handset and audio sources pop up and cadillac cue is selected it reverts back to the iPhone source and the call remains on the headset. I had no luck at my local dealer and the cadillac cue team indicated that their cue simulator is not available to test the issue. This is the number one selling phone in the us and it doesn't work with the cue system... Don't we deserve some follow up on this issue?
