Navigation/Gps

I'm a big fan of this app. It's usually within a 30 feet of dead on accurate.
Alas, it's beginning to piss me off. Of course good things can't last.
I went into the city this past week. And I had a few problems, the biggest being, that the 3d map won't animate!
It got my current location ( which all of a sudden wasn't very accurate ), gave me directions, showed me the arrows and streets, and just wouldn't move after that.
I tried everything to fix it. I un did the hacks to make internet faster, and  nothing. Everyone once in a while, after powering up and down, it would animate for a few blocks, then stop.
What gives?
Anyone else have this problem?

From what I've read, your in the Baltimore area, right ? I am too, but I haven't used my Nav in a few weeks. I'll try it on the way to work tonight, and let you know what happens. Typically the only issue I have with it around here is when I go through the Fort Mchenry tunnel.

Yes, it does. I'm on that plan and can verify that.
