释放双眼，带上耳机，听听看~！
If you have Garmin’s GPS navigation technology, Garmin Express may be very useful. It allows you to update the map on the device, back up all data to prevent loss, and share travel points or routes with other users of these devices with just a few mouse clicks.
To work, you need to connect the device to the computer, and then open the program. It will automatically recognize the navigator, and then select the required operation in the application window and wait for it to complete.
