D2 Delta - version 7.00

NOTE: the update file is not available in Garmin Express and it appears as corrupt when using WebUpdater. I've reported this issue to Aviation Support and will update this post with any further information. If you want to install the update manually, direct message me for instructions.

Garmin has released version 7.00 for the D2 Delta series. From Garmin's "Updates & Downloads" pages for the various D2 Delta devices (see below for individual links), the consolidated list of changes are below; where a feature only applies to a specific device it is so identified.

Changes made from version 6.10 to 7.00:

  • Added support for Explore Navigation Sync, where one can select lines, waypoints or generic points on the map within the Explore app and start navigating on device.
  • Improved the Garmin Pay experience on device.
  • Improved the accuracy and reliability of altitude data.
  • Fixed an issue where one wasn’t able to create custom alerts within an activity.
  • Fixed distance and time values for tracks/routes synced from Garmin Explore.
  • Fixed an issue where Training status would no longer update via Physio TrueUp.
  • Fixed an issue where steps would intermittently stop accumulating after a multisport activity.
  • Fixed an issue where one couldn’t edit Wifi networks, if the device had not paired and synced with a Garmin connect account.
  • Fixed an issue where screenshots generated from device did not look right.
  • Fixed an intermittent issue with Livetrack.
  • Fixed an intermittent issue where the device may freeze while using Garmin Pay.
  • Added support for CIQ SDK 3.2.
  • Fixed an issue where the device would intermittently fail to save an activity.
  • Fixed an issue with Livetrack auto start.
  • Fixed an issue with bike lights staying on during non-cycling activities.
  • Fixed an issue where the elevation plot would intermittently double the distance while navigating.

  • continue to maintain a list of bugs, requests, fixes and workarounds. 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
    • [WATCH] sunrise/sunset calculations appear to be incorrect
    • [APPS] HSI data screen is missing from the FLY app
    • [GPS] cannot receive a GPS fix within the flight deck of an Airbus A-320 (and several other aircraft)
    • [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] METAR widget does not calculate the runway headwind/crosswind components properly (runway magnetic heading is used with METAR wind, which is true heading)
    • [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:

    • [WIDGETS] METAR widget does not handle one-way runways properly when displaying runway wind information [fixed in 6.10]
    • [WATCH] add support for Galileo GNSS
    • [WATCH] add support for Spotify (feature request, added in FW 4.50)
    • [WATCH] pop-up first-time help/hint bubbles are displayed after every reboot and/or sync [fixed in 5.40]
    • [WIDGETS] Altimeter widget ignores the widget configuration for display units of "feet" when general watch config is set to metric [fixed in 5.40]


    Old issues [could not be confirmed or appear to work as expected]:

    • none at this time

  • Just downloaded via WebUpdater and it installed with no issues. Perhaps Garmin have fixed it. FW now at 7.00 (a0717f4). All working as expected. Garmin Express however states it's still at 6.10 but doesn't seem to affect operation of software.

  • For me it does not work at all. At least on Mac. Webupdater doesn't even recognize my D2 if the USB is switched to MTP. If the USB is selected as "Garmin" D2 will connect but I got the "File corrupted" message and game over. 

  • I still cannot download the WebUpdater. From where did you download it ?

  • Exactly the same here. Is this only on Macs?

  • Don't bother updating all, wait until 7.10 (or whatever comes after 7.00). The altimeter bug is a real issue and whilst it was merely an annoyance for me (i'm not a pilot), it may be quite troublesome for pilots using the watch for it's intended purpose. This may also be why it is unavailable on the Connect app. I have regressed my unit back to 6.10 and all is well again......

  • Thanks AvoOhanian. Will wait for the next release. cheers.

  • So, version 7.10 is there.

    Same issue trying the webupdater on Mac: "file is corrupt"

    Anyone any ideas?

  • Got 7.10 running now.

    Point was to say "yes"to "set to MTP"? when attaching the D2 to USB.

    So, finally worked!
