Garmin 760

I got my 760 for about $325 delivered and one can find the unit with backup cam for $400 or so. Most GPS problems go by by when one reads the manual. Although I have seen over the years some strange things. Like get off freeway, do U turn, now reenter freeway. But as said before LOOK AT YOUR ROUTE zoomed out far enough you can see what the GPS is doing. Millions of pieces of data tied together to make a route. One favorite of mine is when doing shortest route the GPS will have you go trough a town because going around on the freeway is longer or shortest time take you over a goat trail. GPS only does(for the most part) what you command it do.
