Garmin is a manufacturer that offers an array of GPS and navigation equipment. For a GPS to work properly, you must ensure that you have an updated map. If the map file in the GPS is outdated, you may be unaware of different routes and changes within roadways. Garmin offers free map updates periodically depending on your GPS and how long you have owned your unit. You may also purchase map updates from Garmin on their website.
Set up an account on Garmin's website by going to their website and clicking on the "Create New Account" button. You must have an account on their website in order to register your GPS and to download maps.
Connect your GPS to your computer. Refer to the manual that came with your GPS for specific instructions regarding computer connections. Most Garmin units come with a connector, such as a USB cable, that connects to the unit and into the USB port of the computer.
