I have two Garmin units. I also have Streets and Trips 2011 with GPS sensor. Besides this I have an Ipad with GPS and also apps on mine and my wife's Verizon smart phones. None of the above, with the exception of Streets and Trips, have any warning about overhead clearance.
After three years of comparing routes calculated by the different devices I have learned to rely most on the routes calculated by Verizon. It does not always give the shortest route, but when I have depended on Garmin rather than a different route calculated by Verizon, it was a mistake. The Garmin has put me on mountainous routes such as one just north of Santa Rosa, CA that limit speed to 25 mph for miles, when the alternate Verizon calculated route, although longer, would have been much safer and faster. The only drawback with the phone is that it must have a signal to calculate.
