Morning all. I've just had a replacement NTG 4.5 installed and coded to overcome the anti theft protection warning, works great now but the Navi doesn't work as it complains that the map data doesn't match the Comand version. Having done some reading online, I believe there's a chance I can download the maps that are already installed on my car and simply insert an SD with the exact same maps and have the system re install the maps without asking for a pin. Trouble is, I don't know how to ascertain what maps version I have at the moment as I can't get into the nav screen. I have downloaded Comand download manager but the only map It shows me for NTG 4.5 is v19, is there anywhere I can download older version of the maps from? Cheers
