ApproachX10 is what I use for the golf course, and I do update my device with Garmin Connect™ and Garmin Express application. I make Garmin map updates on Approach X10 by following these steps:
- Connect your device to the computer with the help of a USB cable
- Install the new software using Garmin Express application on your device.
- Just don’t disconnect your device from the computer until it downloads the software.
I hope it’s clear now! For better advice on Garmin updates, check their website.
