I have the 760 with up to date maps. All I have to do is turn it on and it will get me lost. I will never trust it again. I use a trucker's atlas to plan my route and use the GPS to look ahead for diesel, food, etc. My phone has a better map program. The last time I was on I40 in Oklahoma it kept telling me I had to exit as there was a low bridge ahead (I'm under 12 feet high). I noticed the 18 wheelers were not exiting so I decided to take a chance but the Garmin kept telling me to exit. Made it all the way to New Mexico and never saw a low bridge. It has done similar mid-directions many times. Just saying...
