Mine worked fine with 6+ as well, and now only sometimes with my 7+, although I rarely make outgoing calls. Anyways, with 6+, no problems, but with 7+ I can't answer calls anymore. Well, I can, but I can't hear anything, either from phone or from car speakers. Before I would answer on touch screen of car and be able to talk. No I still can do that, but I won't hear anything, and trying on the phone doesn't work either. If I answer from phone while in car, same thing, I can't hear from phone or car. When someone calls me now, I just wait for the ringing to stop then call them back from the phone. I can't make outgoing calls from car anymore and I'm tired of trying to figure out. Worked fine with 6+.
