Has anyone used a Garmin in Pittsburgh and if so, how well does it work? I am most interested in how it works in the city.|||If it's anything like Mapquest and a few of the other map sites, it will be a horrible experience. In the hilly part of town there are stairs that are legal streets. The City maintains them. There are houses along them. And they have street names. But they are stairs none the less. However, Mapquest has a bad habit of trying to get people to drive on them. So if you do follow any GPS system or internet directions, make sure that the street you're to turn on to is actually a street.
