I dropped my handheld yesterday an it still works an all but there's a thin black line running across the screen is there any thing I can do. It's not a crack in screen but there's a line across it horizontal. Jus asking

Send back to Garmin plus around $115 and they will send you a re-furbished one that's what I had to do

You may try clicking "RESTORE DEFAULTS" in the pages at the bottom of the maps screen before sending back.
