I have 2 discs. First is labelled NAVI software System 1:8.0 / Mk2 System / Mk3 Top 6.3/ Mk 3 Rad 5.1
2nd Map disk 2019 High. Discs came with car but look as if they are copies.
Tried reinstalling it, option for language came up, but no change. No speed camera function. No SET option. No language option on screen
I understand I need the install disc for Mk IV from what Autotech are telling me.
I will try the satnavupgrades company
Thank you both for your assistance.
