Was working seamlessly 90% of the time, and now only music works reliably. I can use phone to make calls soon after start but car will fail Bluetooth phone connection and say no phone connected, but I can go to Bluetooth music and play songs. Phone fail will continue no matter what till car is turned of and started. Frustrating to be mid call and have car blow the Bluetooth connection, and while you are trying to put call to speaker before they hang up the music returns from XM radio, so you pause the music and after a bit on speaker phone the car picks up the Bluetooth again and then fails again... End up disable Bluetooth on phone to get car to leave alone. Maddening and dangerous sequences while driving. Enough to make me want to sell my new car!!!
