Mazda Sanyo NVA-sd8110 satnav.
I have recently purchased a 2013 Mazda Mx5 with the Sanyo NVA-sd8110 satnav installed. I need the serial no, to register the device in my new account with TomTom. Can I find the serial no, in the onscreen menus. I would appreciate some help in locating the serial no please.
