The Garmin C320 Rules
Have used this device for the past few weeks and it has saved me time money and posibly my life, before I had this I would have lots of maps and directions open next to me in the car and once i was on a straight road and no other cars on it and had to breifly look down to get my barings and almost drove of the road, gone are those days now, with the street pilot C320, Thanks Garmin great work
