My friend had a TomTom that kept telling her to make a u-turn if she didn't follow the directions. My Garmin just says "recalculating" and lets me go my way. I also bought the lifetime map updates, four times a year.
Um Skyguy79... if Z even has a cell phone, I'm betting it doesn't have GPS. Trust me on this.
Z, although the Garmin comes with a mount, I never installed it. I don't like that people can see the windshield mount and know you probably have a GPS unit in the car. I have found that if you just leave the Garmin on the console, it picks up the signals just find. I do plug it into the cigarette lighter.
Please let us know if you buy one and how you like it
and if you want me to come over and show you how to use it when I come down.
