Apple Maps voice directions doesn't work when bluetooth is on
I have an iPhone 11 with the latest iOS updates. Apple Maps seems to need to have bluetooth turned off in order for the voice navigation to work. Otherwise, all I get is the visual display on the phone -- not good when you're trying to keep your eyes on the road.
I've tried turning bluetooth on and off several times. I'm trying to use bluetooth to connect to my car's speaker system. Using the car's speaker system, I can make and receive phone calls when bluetooth is on. But Maps doesn't seem to like bluetooth. I've thought about doing a Reset. Will I lose my contacts?
Any suggestions?
