Updating your tomtom
The free PC based software can be downloaded from here, `My Tom Tom for new devices and Tom Tom Home for older devices.
A rung below Tom Tom’s flagship GO 930, the GO 730 offers a ever-so-slightly shorter feature set, and purely superficial aesthetic color swap, in exchange for a price cut.
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.
