The Garmin GPS is one of the most used devices in marine, outdoor and turn-by-turn directional driving. One of the best ways to keep your Garmin GPS current is to update the maps on your SD card. When you need to update your maps, you have one of two approaches: update your maps through the WebUpdater application from the Garmin website, or buy updated SD cards from Garmin and install them into your GPS.
- Skill level:
Go to the Garmin website (see Resources).
Click on the "Find Accessories for My Product" drop-down menu, and select your product from the choices. Click the "Go" button.
Click the "Accessories" tab in your product page, and then click the "Data Cards" tab at the bottom of the listings. Buy your SD card through the company's website.
