When I turn on the Stratus 3, all three lights come on. Then, the ADSB light goes off and stays off. Took it up flying yesterday and got no traffic in the air. The ADSB light never came on. Is it toast?
I was surprised just a few months ago to see that the Stratus 3 has been discontinued, replaced with Stratus 4. Has a few more bells and whistles such as a color touch screen display, Apple Find My Device, and a G meter, all of which are things that don't really appeal to me. I just want simple - stick it on rear window, turn it on, it works.
I'd reach out to Support and see what they say. But while you're waiting for a reply, it wouldn't hurt to download the firmware, even if you have the current version, then 1) do a Factory Reset 2) install the firmware you downloaded. That might fix the issue.
