Some TomTom navigation devices have a memory card slot that is located on the side or bottom of the device.
When your TomTom Rider is up-to-date, you can use a memory card as extra storage space to add extra maps or to store routes and tracks to your device. Maps can be purchased from tomtom.com.
Important: Routes and tracks cannot be stored on the same memory card as maps because different memory card formatting is used.
