Adding new device Rider 400
Hello I purchased the Rider 400 device second hand. I reset the device and logged into my mydrive account on the device. Now when I go to the mydrive website and log in it doesnt show my new device and it doesnt give option to add device (the car satnav comes up fine). I have connected the device by usb to my laptop but mydrive still doesnt recognize or allow me to add it. How can I add the Rider 400 thanks?
