Updating a built in sat nav mazda

Koolkaz

I have bought a second hand Mazda with a built in Sat Nav. I have bought new UK maps but because it's a built in Sat Nav I can't plug it into my laptop to download the maps. What do I do?

Have a look at page 10 of the NB1 manual http://download.tomtom.com/open/manuals/Mazda_Navigation_System_NB1/refman/Mazda-NB1-EU-LIVE-RG-v4-en-gb.pdfat
but if it is a NVA system look page 86 of the manual http://download.tomtom.com/open/manuals/mazda/nva-sd8110/Full_Manual_EN.pdf
