Did you ever think of getting a refurbished navagation system? MyMy brother did and he is so pleased. He ordered it from Circuit City on-line. Even though the stores have closed Circuit City still exists on-line. I just priced the new Navagon and brand new this goes for $200.00 - $300.00. He got his for $99.00 and it works perfectly. He can use this in his car, on his bike, or hold it while walking on a hike.
We have the garmin, and the Navagon is better in so many functions. My friend has the Tom Tom and the Navagon is still better. I know the ratings say otherwise, but I will be spending $99.00 to get one of these systems.
