I got my D2 Mach 2 at April 1st, the version of the aviation database is cycle 2602. WLAN is on, automatc update is on. As far as I know, the current version of the aviation database is cycle 2604 (since April 9th). When searching for database updates manually, the message appears, that no updates are available. Did anyone here get a newer version of the database? If yes, how to do the update?

When reviewing historical flights, heart rate and heart rate zone data are not very useful, because during a flight the pilot is normally seated in the cockpit and the activity is not being evaluated as physical exercise. Instead, it would be much more useful if the Fly activity history prioritized aviation-related data such as: Vertical speed Altitude relative to terrain / height above ground Heading Bearing These metrics would provide much better post-flight analysis and would be more relevant for pilots than fitness-oriented metrics. I suggest applying this change both on the watch and in the Garmin Connect app, so that Fly activity history reflects operational aviation data rather than standard fitness data. Thank you for considering this improvement.https://forums.garmin.com/pilots/aviationportablesandwearables/f/aviation-watches/434164/garmin-connecct-flying-appSat, 04 Apr 2026 04:35:00 GMTa9571b57-dd57-479e-8763-8f8a603e40aa:4c3d8e62-ac62-483e-b88c-b9084d99e507jmescalanteDear Garmin Aviation and Garmin Connect Team, I would like to submit a feature request regarding the Fly activity on the D2 Mach 1 and the way historical flight data is presented both on the watch and in the Garmin Connect app. When I review historical flights, I currently see health-oriented metrics such as heart rate and heart rate zones. In the context of most flights, this information has very limited operational value, because the pilot is typically seated in the cockpit and the activity is not being evaluated as a fitness effort. For flight review purposes, I believe it would be far more useful if the historical Fly activity emphasized aviation-relevant parameters instead. In particular, I would suggest prioritizing the following data fields: Vertical speed, Ground speed, Altitude relative to terrain / height above ground, when terrain data is available and Heading. These parameters would provide substantially more meaningful post-flight insight than heart-rate metrics for pilots reviewing a flight. They would help users better understand climb and descent behavior, aircraft energy management, terrain awareness, and directional control during different phases of flight. My suggestion is to remove heart-rate information completely, to allow aviation-specific metrics to replace or take priority over fitness metrics within the Fly activity summary and historical flight review screens. Ideally, this improvement would be implemented in both places: On the D2 Mach 1 watch and In the Garmin Connect app. From a pilots perspective, the Fly activity should present post-flight information in a way that reflects the operational nature of aviation, rather than the fitness-oriented logic used for running, cycling, or other exercise activities. Aviation users would likely benefit from having a dedicated post-flight review profile in Garmin Connect, where aviation metrics are treated as primary and physiological fitness data as secondary or optional. Thank you for your continued development of the D2 aviation ecosystem. I hope you will consider this enhancement, as it would make the Fly activity significantly more useful for pilots.https://forums.garmin.com/pilots/aviationportablesandwearables/f/aviation-watches/434163/the-heart-rate-zone-are-uselessSat, 04 Apr 2026 04:34:00 GMTa9571b57-dd57-479e-8763-8f8a603e40aa:0d7d3007-d8d5-4a03-ad11-311bb6711897jmescalanteDear Garmin Aviation and Garmin Connect Team, I would like to submit a feature request regarding the Fly activity on the D2 Mach 1 and the way historical flight data is presented both on the watch and in the Garmin Connect app. When I review historical flights, I currently see health-oriented metrics such as heart rate and heart rate zones.

Flight plans are no longer synchronized to the watch. What I already checked: - The connection between the watch and Garmin Connect works normally. - Garmin Connect and the D2 are both connected correctly. - iPhone and apps were restarted. - Garmin Pilot and Garmin Connect are updated to the latest versions. - I also reloaded all databases in Garmin Pilot. Despite all of that, no flight plans are transferred to the D2 anymore. Before this it worked reliably, so something must have changed recently. Has anyone experienced the same issue or found a solution? Is there a setting or reset step I might be missing? Thanks for any ideas.https://forums.garmin.com/pilots/aviationportablesandwearables/f/aviation-watches/432347/d2-mach-2---software-21-27---crash-during-runTue, 03 Mar 2026 20:51:00 GMTa9571b57-dd57-479e-8763-8f8a603e40aa:972bd8d6-84ab-4b8f-a75d-f90af12ae74fSteveA-NZD2 Mach 2 - crashed 24 minutes into a run, and took a couple of minutes to restart. https://connect.garmin.com/app/activity/22049063678 Data there show's the break where it happened.

Also, temperature, cloud and precipitation readings on the weather radar seem to be correct. Anyone have any idea why this info is off? For what it's worth, current actual winds are 16006KT at the airport (as shown in the METAR report and weather widget) and 180 at 8kt local, but the radar is showing roughly 040 at 11kt (both local and at the airport).https://forums.garmin.com/pilots/aviationportablesandwearables/f/aera-aviation-portables/408746/adding-custom-features-as-a-visual-reference-to-the-basemap/2000595Mon, 05 Jan 2026 20:40:00 GMTa9571b57-dd57-479e-8763-8f8a603e40aa:5d8c584d-b223-49c3-8eaa-385224f0bb45Garmin-ZMHello, Below are the instructions on how to create a boundary on your aera 660 in BaseCamp. 1.
