Updating a Garmin GPS unit is an easy job, but it can't be updated while you are on the road driving with your friends or family, because you'll need a desktop/laptop and a USB cable. Follow the steps given below to update almost any Garmin GPS Device.
Step 1: Download Garmin Express
Download the free Garmin Express software from the Garmin website. The software requires Windows 7 SP1 or newer or Mac OS X 10.10 or newer. It's designed to work on all fairly recent Garmin GPS units, so there's no need to hunt for a version for your specific Garmin device.
Note: Your computer must have internet access in order to download the program and to find updates for your GPS unit.
Step 2: Connect Your Garmin GPS Unit
Connect your Garmin device to the computer using a USB cable, then run the Garmin Express software. Click the "Updates" tab in the software window, and Garmin Express will find all the updates available for your GPS unit.
Step 3: Download the Applicable Updates
Once Garmin Express has found all updates available for your device, choose whether to download them all at once or to download only specific updates. If you're in a hurry and need maps for only a specific region, for instance, there's no need to update all the maps in the United States at this time; select only those you need immediately. It's also a good idea to install any software updates indicated by Garmin Express, as these help ensure that your GPS unit runs smoothly.
Note: Do not turn off your computer or remove the USB cable from the computer or the GPS while updating, or the process will fail.
Step 4: Wrapping Things Up
Wait until Garmin Express states that all selected updates have been completely installed; this could take some time, especially if you haven't updated the unit in a while. Once all updates are complete, your Garmin device is ready for the road once again.
Note: Sometimes the update process fails, usually due to an update needed to the computer's operating system. A Garmin Express notification will inform you if a Windows update is needed, for instance, and will guide you to the location of the relevant patch. Reattempt the Garmin update after you've installed the operating system update.
