we be very happy with we purchase and the price be right ! there be a couple of glitch with the map but that be probably a satellite problem . for instance ... it seem to think we house be on the leave when it be actually on the right . then I use it to go to a newer area of we town and none of those street be in the satellite . that will probably happen sooner or later . I purchase a 2 gig SanDisk for $ 35 in order to download the entire United States . the system come with a 128 mb .
