So i went to Radio Shack to compare the two units. The TomTom XXL 550T ($99 Black Friday Price) and the Garmin 1450T ($150 Black Friday Price). Which one works better and is more reliable. Whatever unit I decide will have to be able to run Trapster! I need something better than my old 3.5" Motorola POS. I just dont know which one is better? If you have used a device from both companies please list ur opinions?
