HI ,NEW HERE, when i turn my tom tom on it comes up with no maps found ? i went to update my maps from the quarterly service and it couldnt download them as there wasnt sufficient space so thought i would remove some stuff as in "old maps" after doing this it has stored maps on my comp , and when i try to download them from comp it still says insufficient space ,why is that when the maps are on my comp ?? and theres hardly any space used at all with other stuff voices etc, i have tried looking through the forum for answers but its mind boggling and dont really know what im looking for ,is there a way to delete everything then upload it all again ,if so please explain slloowwllyy ,not to clever on these things so may need it in laymans terms , many thanks,
