You connect your sat-nav to your PC or Mac using the USB cable that came in the box.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.Download the latest map at no additional cost within 90 days of vehicle delivery.
Actually, the most common reason for errors in route calculation is due to the outdated maps.
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.
Garmin have made a number of changes to their map update procedures in the last year.
For those with newer devices these changes have made it much simpler, for others it can still be a painful process with numerous calls to Garmin technical support.
You have an option to purchase either a one-time map update which currently costs €59 or lifetime map updates which costs €89.
