Garmin has released Beta Version 16.05 for the Instinct 3 series, Instinct E, and Instinct Crossover AMOLED smartwatches, according to a report published by Alex Alderson on September 27, 2026. The new firmware serves as the second update in the current v16.xx beta development cycle, following the rollout of Beta Version 16.04 roughly a week prior.
Rollout Details and Manual Installation Requirements
Users cannot receive Beta Version 16.05 through automatic background downloads. Garmin distributes the firmware strictly on a ‘Check for Updates’ basis. Owners of compatible devices must go through the main menu on their watch, select Settings, open System and Software Update, and then tap 'Check for Updates' to initiate the manual download process.
This update follows a quick succession of software releases for the rugged smartwatch lineup. On September 24, 2026, Garmin deployed System Software 15.19 for Instinct 3 series smartwatches running stable software. That stable release was preceded by Beta Version 16.04, which kicked off the v16.xx development phase.
Changelog Silence and Sensor Hub Firmware Version
Garmin has not disclosed specific functional changes or bug fixes included in Beta Version 16.05. Instead, the company repeated the changelog from Beta Version 16.04, which brought Sensor Hub firmware up to version v41. When Beta Version 16.04 launched, it introduced a new Recovery Mode, improved Wave Detection, and bundled two fixes for bugs found in older firmware.
Because the manufacturer left the changelog identical, at least one member of the Instinct 3 community has asked Garmin directly on the company’s official forum for more details regarding the contents of Beta Version 16.05. At the time of release, no further details have been provided by the manufacturer.
