Enduro 3 boot loop May 2026

Hiya,

Just adding to the other threads - last week enduro 3 entered a boot loop cycle blue triangle of sadness, unable to soft or hard reset, returned from abroad to laptop and unable to boot while attached to mac. Now seeing this is likely related to this week's map update - less than ideal.

See a possible fix is waiting for battery to drain, which will take, I guess 4 weeks or some sort of garmin update.

Advise not updating your garmins friends

  • Personal experience: I updated the maps on my Enduro 3 on the beta firmware (22.28 currently) using Garmin Express and it thankfully did not boot loop. This of course doesn't rule out some issue with the current stable firmware, but it's at least a data point.

    Probably not relevant, but I also have a "gmapsupp.img" file on containing my custom local area map.
