This is the TomTom XXL 550M Auto GPS. With almost two decades of experience in navigation software, we deliver the most intelligent and innovative navigation solutions. Our GPS devices are the only ones with the technology to grow smarter each day, so that you get to your destination. TomTom maps include over a million more miles of road in the US than the competition. Other GPS devices may send you into traffic because they calculate routes based on static posted speed limits that don’t account for routine traffic patterns. TomTom’s exclusive IQ ROUTES™* uses “real world” driving speeds to always get you on the smartest, fastest route based on the time of day and day of the week.
