I recently upgraded my iphone to the iphone SE model and went thru the car setup as done in the past. The phone recognizes it no problem and I can make calls out without a problem (from names entered manually into the system). The problem is incoming calls. It rings thru the speakers and I hit accept call and 9 out of 10 times won't connect. I have to manually accept the call on my phone and then hit audio source and hit acura phone system and then sometimes it connects. My old phone never had this issue with incoming calls. Any ideas? I wasn't sure if this was an apple software issue or bluetooth connectivity issue?
