I am curious about something else, since I am on the subject of the (Uniden) GPS device. I am wondering if I can use it day-to-day to "tell" the scanner where I am, as opposed to entering in my Zip Code. I live in the Houston area, but drive a considerable distance around town everyday. So, I am really not just limited to the Zip Code that I have entered in to the scanner. So, the question is, using my regular profile, with my everyday Favorites Lists, would I be better to plug in the GPS unit and use it all of the time? If I make a trip out-of-town, I would change profiles, so as to turn on the entire Nationwide database.
