My D2 Delta has the blinking blue triangle. I’m an instructor pilot for the military and use and depend on the watch for nav routes and various other things. I have followed all instructions for soft reset, restart and Garmin Exspress, none seem to work. As an example Garmin express will not even recognize devices when “add device” is selected. I made sure to have a Garmin brand connector and actually tried a second Garmin connect with no luck. I can’t even begin to express my absolute frustration with Garmin. This is my second D2 and unfortunately probably my last.
