Updating the maps on your GPS device used to be a complete pain in the butt.
You'd have to order your update on CD, DVD, or SD card and wait for it to arrive in the mail.
Insert one end of the USB cable into a port on your computer and plug the other end into your GPS device.
Click the "Start" menu and select "All Programs." Open the "Garmin" folder and click the "Web Updater" entry.
It also offers points of interest, live traffic updates, lane assistance and many other features.
To keep your maps accurate and the device's software running smoothly, you'll need to perform an occasional update.
Web Updater then searches the Garmin website for compatible updates. You can then choose the updates that you want to install.
If you have lost your USB cable you can get a replacement. Within Garmin Express, selecting 'Install All' under the 'Updates' tab is the safest option.
Even with several years of updating various models of Garmin sat-navs, I have found the experience torturous at times.
You buy a micro/SD card preloaded with the Ireland/UK maps, you insert it into the side of your device and off you go.
Garmin suggests updating your GPS with the Web Updater tool.
This tool, available from Garmin as a free download, recognizes your GPS when it's connected to the computer.
