I am the new owner of a CPO 2015 85D. The first couple of days I didn't have this problem, but now I get a weird problem every time I get in the car. The car thinks my iphone 6 is making a call (which means it mutes the radio and brings up the call screen) yet won't let me disconnect through the car interface. The car display shows a call in progress to "My Number", but doesn't let me end the call. The iphone itself shows no call in progress. If I turn bluetooth off from either end (car or phone), the radio goes back to playing normally and all is well, except I have lost phone access. Any ideas? Think this needs to go in for service?
