Personally I think you are better off not updating Maps and More. Changes to the road network take such a long time and rarely cause a problem when using navigation. I read so often that updating has caused problems to users that I don't bother with it.
grab any old pc , low spec second hand, etc all it needs is an internet connection and a usb socket....alternatively, ask a friend....where in scotland are you? I can update your m&m at my surgery if you pop in
