Garmin nuvi 350 3.5-inch portable GPS Navigator  it have some nice extra , like a audio book reader , a photo viewer -lrb- do not use -rrb- , & a mp3 player -lrb- have not use yet -rrb- . but the basic mapping and trip planning be accurate , easy to follow , easy to program , with clear graphic . I have have it cut out briefly in isolate mountain area , but that be unavoidable -- it last a lot longer than my cell phone ! I highly recommend Garmin , and the nuvus 350 in particular .
