From their device, users can select whether to list gas stations by location or price, and can request the lowest gas prices on their route, nearby or within a user selected mile radius. Travelers can also choose which type of gas they would like tracked, Regular, Midgrade, Premium or Diesel. Updated gas prices for that specific type of fuel will be downloaded automatically over-the-air through a Bluetooth phone or when connected to TomTom HOME on a PC or Mac.
TomTom receives its fuel data from OPIS, via INRIX Inc., a leading provider of traffic information in the United States. These companies receive daily feeds through credit card transactions and directly from gas station owners at nearly 120,000 locations.
