I always face two Issues with my Infotainment System whenever my iphone is connected via bluetooth:

1- after a phone is complete the screen remains stuck at "Call in progress" and never changes back to the main screen. Sometimes it does come back after i press the HOME key and sometimes it remains stuck until i restart the car.

2- Again, whenever I connect my iphone the car audio player plays automatically whatever is stored in My Music. This happens all the time and there is no way around it except to turn off the car Audio completely (pressing the round button on dashboard). This is very annoying.

Both issues have been reported to my local dealer and they say there might be a fix (software update or infotainment screen replacement...) something like that but i havent yet taken an appointment. They also told me couple more customers reported the same issue.
