well , I be not go to write volume since other people have pretty much express a lot about it . I will say this be my first gp and I love have one . I go on numerous trip and often arrive late at night in big city I be unfamiliar with . it have save I on numerous occasion . if you ever even wonder if a gp could help , trust I , it will . however , my biggest gripe be the voice recognition . I feel I enunciate well and that my grammar be good . this little contraption be terrible when it come to recognize voice command . I have friend and family try to talk to it and it do not understand any better . I think this feature would be nice since I be a stickler for no texting and that include punching in road command . as for find road , it be about 98 % accurate with obscure side road be a problem except one major road in Chattanooga that it could not find because it know it as a different name . I also do not care for traffic too much . I go through all kind where I live and nothing be on the device to indicate it . other than that , a gp be worth its weight in gold ! I agree with other people on here that this particular unit be not worth the extra money . find another that speak to you -lrb- very nice -rrb- but wait for extra bell and whistle till Garmon get the quirk iron out .
