I be really please use this unit . it do its job so cool . there be a 2 gig memory on it and you can put you music -lrb- mp3 's -rrb- or picture and everything . its shape be also great I mean it be not way too big . screen and color be perfect ! there be two thing that I dont like so far . the First one be the antenna . you have to open it up at all time to use while drive . while open it make a little noise which bother I . another thing be right after I get this unit , I drive to NY . when I be in manhattan , sometimes it couldnt find the point that I ask . finally it be find everything but I guess sometime these thing might happen because this gp be not the most expensive one . when you compare the unit and its price its just great ! BTW if it get stick , just reset it ! I have do just one time so far .
