Some TomTom navigation devices have a memory card slot that is located on the side or bottom of the device.
Before you use the memory card slot, make sure that you have the latest version of the application installed on your navigation device by connecting to MyDrive using a computer.
When your GO is up to date, you can use a memory card as extra storage space to add extra maps, tracks or routes to your device. Maps can be purchased from tomtom.com.
