I already have a gmapsupp in my Garmin folder which works fine. Garmin and the mapping works perfectly, I only want to add this one as the maps are meant to be more up to date.
Can someone please explain the procedure?
I also have sw.unl and gmapsupp.unl which was needed when I unlocked the old map IIRC. Do I keep them or delete the lot and just add this new gmapsupp file?
Thank you for the help. I don't want to stuff my perfectly working XT if possible ao any info appreciated....
