the Garmin i3 be exactly what I be look for in a GPS unit ... small , easy to use , reliable and accurate . the StreetPilot software be simple to install on my pc and be current up to about 2005 . I notice some store and restaurant over a year old be not available . however , you can download Points of interest from various 3rd party internet site to update some missing location . if you plan on travel throughout the US I would suggest purchase a larger memory card . the supply 128mb card will only hold about 7-10 state map . overall I be very pleased with my purchase .
