If your Garmin is in error they want to know. I have done this twice now and they fixed the error on the next update. They also responded thanking me for the info. Both of my Garmin's a 1490LMT and my RV 760LMT work awesome. Do not blindly follow the suggested routes if they are shortcuts, it might not be where you want to be. you should have the big picture in your head to start with. I did the original map update and further updates at least twice a year....Try to out wit your GPS, it's hard but can be done......Mike
