I have a Galaxy S6 Edge and a 2016 VW GTI and I've been using Android Auto via USB connection successfully for the past year. Since the Android 7 update a few days ago, the car won't recognize the phone as an MTP device so AA doesn't launch. I've tried a new data cable, installed latest AA version, restarted the VW infotainment system, and thrown like 4 fits, but nothing seems to work. Any thoughts?
