The Web Updater application automatically searches for upgrades and additional maps for your device, downloads the necessary files and installs them directly to your unit for free.Open an Internet browser and visit the Web Updater download page (See "Resources" below.) Click the "Download" button to download the application to your computer.Currently, all Tom Tom map updates are done through either My Tom Tom or Tom Tom Home.The free PC based software can be downloaded from here, `My Tom Tom for new devices and Tom Tom Home for older devices.
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.
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.
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.
Wait for the progress bar to complete before disconnecting your Garmin device.
