What happened to my GPS???

[Evilguppy]

I went to my contacts. Clicked on my doctor's address. Clicked for directions. The darn thing decides it's some kind d of highschool. I figured maybe it's right next to it, so I started driving and followed the directions... ended up 7 miles away at a high school indeed, not anywhere near my doctor.
There was a recent Maps update.
Could this be it? How do I fix it?
