Garmin Express is the GPS device that guide people during their trip be it road trip, marine, air or adventurous trip. The Garmin devices have advance features and are very east to update. Hence, Garmin.com/express is the easiest way for Garmin map updates. I have seen people struggling and yelling on Siri to get the right location. But Garmin gps never let you suffer because you have to do only one thing that is- connect your device to computer using USB and update Garmin GPS for better experience.
