It is important to let this procedure complete - don't be tempted to switch on/off your device even if it looks like nothing is happening.The software update procedure can take several minutes to complete so be patient. It is advisable not to update your sat-nav if the battery is flat, make sure it is charged. Your sat-nav may not have sufficient space for the map update.

Insert one end of the USB cable into a port on your computer and plug the other end into your GPS device.

If all goes to plan, not only will the latest maps for your sat-nav be installed but also the latest device software, Bluetooth updates, voice updates and so on. Register your sat-nav by entering your email address when requested to do so. I recommend that you only use Express if you have a good and reliable broadband connection as some of the maps files are very large and take several hours to download from Garmin. During the update procedure and depending on your device, you may be asked to disconnent your sat-nav from your PC and reboot it (turning it back on).
At the end of the process your sat-nav will be right up to date. This step is the installation of the latest software (not the maps) for your device.
Even with several years of updating various models of Garmin sat-navs, I have found the experience torturous at times.
