See the next post for the list of bugs and such that I am maintaining.
  • I've started a list of bugs, requests, fixes and workarounds that I will try to maintain. I personally have a D2 Delta device but I am unable to contribute to the list for anything that specifically/only affects the Delta S or the Delta PX.

    I've bolded anything that would generally consider to be a serious issue that impedes use of the watch or included functionality (ie. reboots versus display or other issues). Reply below with comments and I'll keep the list updated.

    Outstanding issues / bugs:
    • [WATCH] Altimeter hardware does not seem to properly handle rapid elevation changes, either from lag or hanging (also affects Fenix 5X+)
    • [WATCH] Running Dynamics drops out around two minute mark when phone is connected; workaround: disable connection to phone while running (also affects Fenix 5X+)
    • [WATCH] There is no way to clear the tail number (aircraft registration) once entered into the watch config
    • [GPS] cannot receive a GPS fix within the flight deck of an Airbus A-320 (and several other aircraft)
    • [WIDGETS] Altimeter widget ignores the widget configuration for display units of "feet" when general watch config is set to metric
    • [WIDGETS] METAR widget uses watch setting for METAR visibility -- add configuration option for "visibility" to "Aviation Units" section
    • [WIDGETS] METAR widget displays blanks screen if station (nearest or manually entered) does not have a published METAR (eg. CYCZ)
    • [WIDGETS] METAR widget does not display the numeric value for the TAF visibility, and instead shows "P SM" or "SM" without the number
    • [WIDGETS] Temperature widget does not display the proper density altitude when using metric units on the watch
    • [CONNEXT] Garmin Pilot does not receive the altitude from the watch

    Feature requests:
    • [WATCH] don't display the Nav Data status at the end of the "About" section, but instead display it after firmware version numbers
    • [WATCH] add configuration option for "visibility" to "Aviation Units" section, to allow selection of SM, meters or kilometers
    • [WATCH] add configuration option for "pressure" to "Aviation Units" section, to allow selection of inHG or mb
    • [WIDGETS] METAR widget only displays cloud coverage (sky) information when there is a measured ceiling but should display FEW and SCT when no ceiling is present
    • [WIDGETS] METAR widget "Use Nearest" function should retrieve an active GPS fix rather than using the last known position
    • [WIDGETS] METAR widget only displays the first six (6) periods of the TAF, which I believe is a holdover from the memory issues on the older D2 Bravo devices

    Fixed issues:
    • [WATCH] add support for Galileo GNSS
    • [WATCH] add support for Spotify (feature request, added in FW 4.50)

    Old issues [could not be confirmed or appear to work as expected]:
    • none at this time

    Looks like the update was pulled again? The first 2 links show no updates, the third one shows 4.50 for the Delta PX.

    http://download.garmin.com/software/D2Delta_510.gcd also doesn't work.

    Yeah, I saw it via Garmin Express and didn't grab the list of updates from there as I usually grab it from the web. But by the time I checked the web page the list, indeed the whole page, was seemingly gone. It's easy though to assume that this may be related to the issue that caused the first Fenix 5 Plus release earlier this week to be pulled but we shouldn't really make any assumptions.
  • My watch was updated to 5.10 this morning. I don't see its listed on the updates page. Not sure what heck is going on.
  • I talked to Garmin Aviation Support today and you should not downgrade to 4.50 if you have 5.10 -- apparently 5.10 will be available to everyone (and back on the website) today.
  • i noticed a few buggs with 5.10
    when i restart watch my tailnr on watchface resets to default d2delta.
    some times fly app starts automatically eventhough i set it to not do.
    also after restart i get the tutorial all the time
