Help please. I am trying to use the Arizona Topo on a Garmin Etrex 20x. I cannot get it to display. I even uninstalled it from BaseCamp and reinstalled prior to uploading it to the 20x. I have had it installed on my Etrex 20 for years without issue. I just cannot make it work on this 20x. I would appreciate any help with this issue. I am just trying to load the map into Internal Memory as it will be the only map used on the 20x. TIA
