simply plug it in and it have work beautifully , with three caveat : 1 . it do not always give I what I would consider to be the absolute best route -lrb- when I have test it around my neighborhood -rrb- . 2 . a couple of time it bring I a quarter mile past my destination , and then say I have arrive . 3 . sometimes it seem to take about a quarter a mile of drive before it completely orientate itself , so if I be not sure which way to start , I have to guess , and if I guess wrong , it tell I that it be `` recalculate '' and then tell I how to get there from where I be go . still , overall , I be very pleased . I enjoy map , but this be way better .
