Hello to everyone. My name is Mark Lee, with vast experience dealing with Garmin devices. Many customers ask if a Garmin Express update is required for their devices to work properly. The Garmin Express update is necessary since it enables you to connect your Garmin device to your computer and update it. As a consequence, you'll need to use a Garmin updater file. Even if you don't do anything, Garmin checks the device on a regular basis for updates.
