Navigation waaay off, but Maps "My Location" spot on.

[Houndstooth]

Anyone else have this? The last week or so when I've tried to use navigation, about half the time it will be way off -like a good 10-15miles. It's off enough that it thinks I'm on a different road entirely and plots out a useless path.

But if I shut down navigation and go into maps and do the "my location" option, it nails where I am exactly. Even if I go straight from maps to navigation, it'll be off.

Restarted every time and that doesn't fix it either.
