Save your money, use your phone.
My parents bought my this GPS system for Christmas a few years ago....I've used it once. Once you get the maps loaded it's easy enough to use but loading the maps is a pain and updating the information will cost you extra. The battery doesn't last long enough for long road trips so you'll need the car charger adapetor. My parents have also have this GPS and we've found it often gives them directions for a longer route than what mapquest or my husbands GPS phone app gives. Overall, I'd say it's not worth it. Use your smartphone or get a real map.
