I find GPS navigation to be essential in Puerto Rico because of the few street signs. Both Google maps and Waze had worked with Android Auto to use the Kia car display and speakers, both a big help! Now it has quit working. When I plug in the USB cable the car recognizes that, but after a few seconds it says the phone is not responding.
I've tried everything the web sites suggest, reinstalling Android Auto app on the phone, clearing the cache, restarting the phone, rebooting the car computer, etc. Nothing works.
The Android Auto app on the car is grayed out, but I think that's normal when the app is not connected to the phone. The phone app runs and in fact is a bit of a bitch wanting to take over the phone screen when getting into the car. I think it sees the bluetooth connection start or something. At least if I use Gmaps I can get the audio to work through the speakers with Bluetooth.
Any ideas?
