I just started having a strange problem this morning, no update of my phone or car that I can recall. When I connect my iPhone 5S to my 2015 CX-5 (w NB-1 Nav) the car tries to call my phone. The head unit brings up the phone call interface with my number being "dialed" and it shows an elapsed call time. However, my phone does not accept a call or have any other indication of something happening. I can't hang up the call using the head unit, only by turning off the BT on the phone. Any ideas?
