If you have a new vehicle and would like your device to track it instead of your old vehicle you have to create the new vehicle and link it to your device.

To do this, browse to the Vehicles and Devices page.

Find the device you want to link the new vehicle to in the table labeled ‘Your Devices’, and click on the edit link.

Scroll to the bottom of the Device Details page to the Vehicle Details section and click on the Change Vehicle link. 

Follow the instructions on the next page to create and assign your new vehicle.
