Developers and manufacturers are always making alterations and updates to keep their software as clean and user-friendly as possible. As such, you will need to update your Garmin GPS every so often. To do so, the easiest way is through Garmin Express. This service will automatically download any available map updates straight to your computer and then alert you when they are ready to be installed.
The process to do so is very easy and the first step you need to take is to download Garmin Express on either your Mac or Windows operating system. From there, connect your Garmin GPS to your computer. Once Garmin Express has been downloaded (follow the steps it gives you for the installation process), click on the tab labeled “Updates”. This will show you any updates that are currently available for you and if there are any, simply click update to install it.
