I had the same issue last night and couldn’t figure out what was going on. (I have an ANDROID phone and not an apple.) We just bought our 2014 Buick Encore used a week ago, and when I turned it on last night, it wouldn’t connect to my phone. We stayed in the car for thirty minutes to try and reconnect it all. Unfortunately, I didn’t Google and find this forum with the answers until this morning, so we did not turn off the car while trying. When I paired it this morning before driving, it connected and worked fine on the way to work. I’m glad that I found this forum. Next time I’ll turn off my motor for a few minutes to let the computer reboot. It was frustrating last night. We thought that our new-used car had a problem. So good to know that it doesn’t and we can continue loving it!
