I installed via DM...installed fine, everything downloaded fine, it runs fine, but...
It thought I was in Rome. (Maybe a few years back, but not now.)
It only displayed a map showing Rome and the Vatican, and everything on the map was in Italian (all other UI in English, and I had selected my proper state (CA) and other regional information.
It also didn't seem to see my GPS puck at all...GMaps uses it just fine.
I restarted the app, same problem. Tried a battery pull, and then GPS worked fine to map our location. Have to try voice directions later, but this could be pretty cool, especially for free.
