How to link my TomTom account to a device?

I've recently got a new (used) Renault and need to connect my TomTom account to my Carminat device. The instructions online say to plug it in to a computer via a USB cable, but there isn't one, nor even a port where the cable would go. Can anyone help? I'm trying to update the maps via the SD card but I can't without linking my account to the device, so I am a bit stuck. Thanks
