i have paid my subscription for the year for my NB1 sat nav in my mazda 6, i have updated the SD card but yet when i go to my services it just brings up a loading screen and nothing else happens? I have heard that their were a few issues with this back in 2013 i believe, does anyone know how to sort this issue out?
