Updating the Software on Your Astro with Garmin Express

One of the things that changes on a pretty regular basis is the Astro Software. The Garmin engineers make improvements in the software all the time. Most folks don't know it, but you can update the software in the Astro to the most current version by logging onto Garmin's website. High-speed internet access required. We highly recommend using wired connections only. Connection instability from dial-up, mobile, WiFi, or satellite connections could leave your device unusable.
