I have downloaded the file in question but it appears to be the same as the one in my unit. Tried copying anyway and made no difference.
I stuck an old rider 2 card into my unit and logged in through tomtom home and it has updated a number of files and hey presto it appears to have fixed the clock issue. Problem is there is no glgps file in the bin folder so dont know which file has done the trick. Anyone shed any light please got a trip planned soon but at mo keep loosing signal due to week rollover
