The first time users can update their Garmin device automatically by merely plugging in their Garmin GPS device to the computer via USB cable. Next time, you will have to manually perform the Garmin GPS update
by following some simple steps. Connect your laptop to the stable internet and plug it with the Garmin GPS device. Now visit the Garmin Express website and click Download for Mac or Download for Windows. Further, go to the location where you have saved the file and install them on your computer by following the on-screen instructions. To install the updates on your GPS device, click Add a device on the installed software, and now it will start scanning your GPS and install the updates. Hopefully, you have updated your device as well. If facing trouble, then feel free to contact me.
