I hit a weird situation yesterday. I was driving here in Austin when we had a freak storm that resulted in some flash flooding. I was using Android Auto, and I saw my GPS position in both AA and the built-in navigation get stuck at a location we we'd been parked. At one point, we stopped for a few minutes, and I disconnected the Android phone and it was able to get a good GPS position, but when I restarted Android Auto, it took the position from the car, not the phone. Compass heading was still updating for this whole time, but I didn't get GPS back until after returning home and having the car sleep for a few hours.

Anyone else had something like this happen? I didn't have a chance to try to reboot the entertainment system, so I don't know if that would have cleared things up. I wonder if the thick clouds stopped the car from getting a good GPS fix? I could see this happening, but I'd expect it to recover when the storm lessened.

I've heard of lightning causing GPS signal interference, but I agree with you, it should have recovered quickly.

FWIW the AA protocol prioritizes use of the car's GPS location but can also use the phone's. I don't know what would have to happen to cause AA to switch over, but it must have calculated the car was providing a valid position fix, so didn't change. I wouldn't have thought of it, but I wonder if you're right that rebooting the infotainment would have cleared things up.

I had a similar thing happen today. We drove somewhere a few minutes away, parked and didn’t lock the car, just dropped some school stuff off at a neighbor’s. Got back in and drove away and the GPS was stuck at the location. Creating a route and resetting the infotainment didn’t help. Apple Car Play worked fine, but built in Nav still thinks we’re across town. Letting the car sit locked in our driveway for a while to see if it fixes it.
