Well let’s see what you fine folks have to say about what happened to me today. I have a Garmin 64sx and I am pretty used to the way it works. I downloaded my route out of basecamp along with my way points. Then off to the river driving up the highway. The unit worked 100% correctly. I got to my location that I calculated in Basecamp. The unit guided me through the highways and by ways and I arrived. So, I stopped my navigation and saved the route. I wanted to record my next trek and I did with out issue. Now, here comes the fun! I wanted to go to another river 16 miles away. No big deal I select my waypoint that I calculated and downloaded earlier. I go to create route and it comes up with “Detailed maps do not support automotive, or atv routing”! Hello, Houston, what the heck was this. I made sure I did not have the topo map selected. I did not and matter of fact I only say the maps of Garmin DEM, the world map, but the topo map NA was there. It would not navigate me to the next way point via roads! Lol it acted like I was in an airplane straight shot! I can’t get my city navigator back. I reboot it twice and no joy. I get to the river, and it never updates my route. I can see all the roads on my screen highways state, federal, city, and townships. So, I get home and think o Gosh how did I delete this out of my unit. The ability to navigate was there when I wen to the river, but then it had a brainfart and lost my city navigator map! I hook it up to the laptop and I when I plugged it in my laptop it clearly shows at first only the three maps their topo north America, DEM map, and the world map. At one time it did not show the city navigator. Then I did some update and then everything came back. It was odd as heck. Does anyone know what happened to me through all my ramblings? This all could of bee a real ##%$%^ show if I had been in Montana and in a remote situation!
