Updating garmin nuvi 250w maps
The easiest thing to do is to find the map of your interest ready to use in . Here you have two options, you can copy the file to your Sat Nav memory, or you can use an external SD card: You can now just copy and paste your file to your device.
But it does have an SD card slot so I use that to install all of North America.This installed Canada and border states to the internal memory of the device, but also downloaded all of North America to my computer. (The download isn't obvious on their site, but Google should find it.) Map Install will let you install additional map areas.The whole of North America won't quite fit on the 2gb SD card, but everything from Mexico north will.If you do not want to remove nor touch the original maps (the ones that came when you bought your device), you can play safe and use an external SD card (read more at our “Best Travel Gadgets” post).You only need to create a folder called file in this directory.
