I have gotten the last couple updates for my descent Via Garmin connect, however this update has yet to come through. Most of the other updates usually come through within a day of release. If I go to the Garmin connect web site it still says my watch is up to date with version 6.0. I rarely use a computer and the one I have is old and slow so connect is the best way for me to get the updates but doesn't seem to work all the time.
If Garmin could make the connect app notify you of an update so you can push it to the watch manually that would be superb. I'm not really a fan of the auto update.
