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.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.
If the unit is travelling less than 10mph, location will be updated every 20 feet.There is no software to install - everything is set up and controlled through the password-protected web portal.You can even set up real-time text or email alerts, so if the vehicle (or person carrying the tracker) leaves or entered a pre-set area, you will be notified immediately.In this case you can either select a smaller region that will fit on your device or you can insert a micro/SD card into your sat-nav to hold the maps. If you don't have one, you can purchase one from here. Always make sure you have the latest version of Garmin Express installed before updating your sat-nav. Unfortunately, Garmin Express does not always work.You can check this by clicking the 'cog' icon, top right hand side of the Garmin Express window and clicking on the link in the 'About Garmin Express' panel. Sometimes it has trouble recognising the devices that are connected to it.
