Not a lot of difference between 5.00 & 5.01 anyway. Neither does WebUpdater offer me 5.01 for my 3790 which has 5.00 loaded. If you really don't have it already and you definitely do want it, just download it from this thread, make sure that you [Only registered and activated users can see links. ] in windows and place it in your nuvi's .system folder named as gmapbmap.img only.
