We have the Garmin RV760LMT and it leads us astray about as often as it is correct. I had an old model Garmin and it was always right. We were on I-40 coming through Oklahoma City. The Garmin RV told us to exit the highway due to a low bridge clearance ahead. All of the big rigs were staying on the highway so we did too. The Garmin kept warning me about the low bridge to the point where it asked me to confirm that I had read the message and they would not be responsible for an accident. I confirmed and stayed on I-40 all the way to New Mexico with no low bridges. It constantly directs me onto dirt roads when the paved road I am on is the correct route. And yes, I have updated to the latest maps. I never tow without my trucker road atlas.
