Updating a tom tom sat nav
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.
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.
Additionally, you can change routes and send the desired destination from your phone to the GPS device, which synchronizes automatically.
This application also allows you to save frequently visited destinations as favourites.
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.
In these cases, even though your device comes with lifetime maps, no matter how many times you connect your sat-nav to Garmin Express it informs you that can purchase a map update.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.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.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.Even with several years of updating various models of Garmin sat-navs, I have found the experience torturous at times.
