In the instance where you want or need more maps, you can install them on your computer. The best application to do this is Garmin Map Install, as it will transfer the maps that are installed on a computer straight to a compatible Garmin device. Plus, it can be downloaded for free straight from the Garmin website. Once you have done so, you can begin the process to download the maps on your device.
Go ahead and open up Map Install and select your device and SD card, whichever source that you want to store the maps. Map Install will inform you if all products can fit on the selected device and if so, give you the option to continue or customize. Clicking “Continue” will download all maps that can fit on the device. Meanwhile, clicking “Customize” gives the option for individual maps and certain segments to be downloaded. From there, simply click on “Install” and then “Finish”. Note, if all maps will not fit it will simply notify you to click “Continue”.
