Hi, I don't believe that this is a map issue. I can see the maps on the screen and the GPS will show me where I am on the map. I used it Saterday and I drove about 400 miles ans the map and location functions are fine. My problem is that I cannot enter an address or zip code so I can tell the GPS where I want to go.When I select the :where To option and enter a city name, it is not recognized. I type in the entire name and search and I get a message that the city is not found. The same thing happens with a Zip Code.Expert: Greg A. replied 3 years ago.i, I don't believe that this is a map issue.
