Review on Garmin 770 LMT S Certified Refurbished by Dwayne Pore

This is my second Garmin RV GPS. I used to have a 760 with a wireless backup camera. The 770 is a step up in hardware design and user interface, but it still suffers from routing errors. From time to time he tries to direct me to roads that specifically forbid wheelies or have height or weight restrictions. These roads are typically parkways in the Northeastern United States, but may be common in other areas of the country. (The time will show). I have read many blogs looking for the best device but so far this seems to be the best. I only wish Garmin would take the time to improve their route data. A simple button on the device for the user to report an inaccuracy to warn Garmin seems to benefit everyone!
