Comments about TomTom TomTom One 130 Easy Port GPS, 3.5'' Full Color TFT LCD Touchscreen, High Sensitivity GPS Chipset, Maps of U.S. & Canada:
Purchased a NAV 5 add-on to my Palm from TomTom. Spent several months trying to get the hardware interface to work. Found out that the maps in the TomTom were obsolete. They wanted big $ to get new maps. Don't buy a GPS without a comitment for map updates at no charge!
