Review on Garmin 770 LMT S Certified Refurbished by Brandon Baird

You'd think Garmin would put route restrictions in its mapping system so that cars would only drive on boulevards. Use of an RV trailer is restricted to commercial traffic roads. If you can calculate the weight and height how about finding the right route when a truck towing a wheeled trailer is only limited to commercial roads. I live in Long Island, New York, and when I was traveling around New York, this unit made me break the law by directing me to every boulevard that restricted business. Marketing this device as useful for RV navigation is very misleading. Come on Garmin, you should know better! How about we update the software for this device and make it really useful! I updated the software on 12/20/2019, still the same problem. Support is useless!
