After the latest map update, 2023.20, i think, the gps route calculation seems much slower. I've turned off myTrends and traffic and still very slow. One thing I've noticed is... if I am near my mother's house in queens, NYC, routing is really fast(within in 2-3 seconds) to a friend's house in Connecticut. However, here in Bergen County, New Jersey, same location takes a while to calculate the route. I've re-installed the map 2-3 times and reset to factory setting a couple of times and it does not seem to help. Any idea why.. where you are located makes a big difference in routing calculation speed? This is true for both Drivesmart 51 and 61. GPS has a full signal with 10 ft accuracy from a bunch of satellites so we know it's not a weak signal causing this.
