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 your navigation device has the latest software version installed by selecting Updates & New Items in the Settings menu.
When your GO is up to date, you can use a memory card as extra storage space to store downloaded maps or to store routes and tracks on your device.
Important: Routes and tracks cannot be stored on the same memory card as maps because different memory card formatting is used.
