Sometimes (depending on internet connection speed, time of day) the process could be very long. Pete, you are right it's not your computer and it's not your internet connection. I have three devices and all of them take hours to update, even having the maps downloaded. The USB speed I'm seeing for the nûvi 260W is just 92.5 KB/s!!I then copied the map file, named , to /home/robin/Garmin Nuvi/Map. If I needed to restore it, I’d give it back it’s original name. When it's time, that can be moved to the Old subfolder.You can do this in the terminal or just open your file manager as root (“sudo thunar” in a terminal window) and move the file from your Garmin to the “Map” subfolder. ALWAYS BACK UP the old map in case something goes wrong! Select and download the new maps from It’s easy, just follow the prompts on the screen to select your map by continent, country, state, province, or customize your own. So I selected only my own state for the new map, because that’s really all I need and it’s just a few hundred MB in size. But until you're sure everything works okay, keep that old one around!Even from the outside, it's impossible to miss the amount of equipment in the car -- there are computer monitors and video cameras on the front dashboard. Their cars are updated with high-tech equipment that allows them to collect data on the go, and if there's an area that's inaccessible by car, they'll head out with handheld devices to complete their research. While it's always a good idea to report suspicious activity to the authorities, in this case, you might find out that the group was performing a more innocuous service.
