Jerry,
Garmin is the leader for sure. You can't go wrong. Fortunately, right now, there are a lot of very good GPS on the market.
A Garmin street pilot is a good choice, and you can decide how much you want to spend.
Even if you got the bottom of the line, you would have something that would do what you need it to do.
The more expensive ones have what is called blue tooth, which is probably more than I understand, but it is lots of music to boot.
The best of luck to you,-----Just go to a store and ask or go on line and look and you will find what you want.
Steve
