Good time to update firmware and maps on GPS units. Garmin Express told me which Garmin units required updates. Always good to keep current. Download Garmin Express here: https://www.garmin.com/en-US/software/express/ If you are updating maps, be sure to load a copy onto your computer. If you fish around in "details" on the map update page as you are about to upload to your unit you'll find an option of upload a new map to your unit and to your computer.
