Subscribe to Garmin Alerts

It's simple to subscribe to Garmin's Service and Navigation Alerts service and it will help satisfy the CAA's requirements for software management that's required for PBN navigational approvals.

Simply navigate to: http://garmin.blogs.com/aviationalerts/feeds.html and enter your email address for the alerts you require.  The service document notification subscription is where you will be advised of both the availability and requirements for any new software versions.  But subscribe to all four services as the others will give you a good heads up notification of any issues or anomolies before they catch you out.
