My 1198 is having issues and so am I. I need it for 2 more weeks for work before sending it in because it locks up frequently between changing views and dropping views. It seems to do this when I have any card in the slots while booting up. I have to go into the menus and reset to default and make sure all views are visible just to get a map to load.
Anyhow...somewhere in the menus there is a way to change the GPS coordinates from decimals to minutes and seconds, etc...I did it this morning...but darned if I couldn't find the offering this evening and don't know where to look on the manual. Help!
