GPS directions and navigation audio will work. Then the voice navigation will stop when I answer a phone call. Directions will show, but the voice is not heard. Only the phone call is heard. Android auto is connected, but the audio toggle button turns off. The audio toggle button can't be turn on. I have unpaired the phone, restarted the phone, updated the GMC software at the dealer, updated the android auto app, and reset phone settings. Google maps settings have also been checked and all are on.The navigation voice will not play over phone calls. How can I get the audio toggle button to stay on.
