i had a similar problem. I think it has difficulty searching using GPS while in motion. When I pull over, it works better than when I'm actually driving.
Then again, with 4.5, I was getting a lot of hourglass rotation and freeze ups with vz nav just by opening the program. I thought my memory was too full but that wasnt the case. I deleted it and reinstalled it and it works much better now.
Now that I notice it, I have not done that since the upgrade to .77 so that "just" might be the issue
Ok, i use VZ and wanted to test mine out. Mine worked ok, like it did before the upgrade. The screen didn't time out or anything it just stayed lit and gave me directions.

Not sure what it all means really. i set my security time out at one minute to test, then began a trip navigation. It wasn't plugged into a car charger. i wasn't driving just sitting here.
