I have a Garmin 420 that has both the Nav data and Terrain cards. The Terrain card causes an error to be displayed that says "Invalid User Format". I really don't care if the terrain is on there or not and don't want to buy the update so I have removed it. Now there is a hole. I know that there are blanks to fill the slot but Garmin won't sell me one direct and the local Garmin dealer can't find the part number for it. Does anyone have one that they are willing to part with?
