Three issues if anyone can help:
1) I start navigation, then some time goes by, the screen goes dark, and I'm locked out of the phone, while driving I have to log in, very annoying.
2) I take a call, and then navigation does not continue helping. It stops and I miss the destination. Is this normal?
3) at the end, it says you have arrived, but the address, which I'd like to see on the screen, in not there. The app quits.
