Review on ✈️ Unlock the Skies: Garmin D2 Air - The Ultimate GPS Smartwatch for Aviators by Steve Hardy

As many reviewers have said, the GPS does not work immediately after installation. Called customer service and they didn't help and didn't seem to care that I was planning to return the watch. Here's how I fixed the GPS: 1) Press and hold the bottom button 2) The menu appears 3) Scroll to Settings, Aviation, METAR location 4) Select Next, wait for the GPS list to appear , and select a location near you. I'm glad I got it fixed because otherwise I really like the watch. Aside from being dependent on my phone, they are just as functional and better looking as other Garmin flight watches. The O2 sensor works well but drains the battery a lot so I only use it when I'm sleeping. Haven't had a chance to test it in the air yet, just received PPL.
