Garmin’s latest Edge rollout, Series Version 28.20, lands with the long-promised 5Hz GPS recording to boost tracking precision—an exclusive for the Edge 1050—and a solid set of upgrades for the Edge 540, Edge 840, and Edge 1040. Bundled as the August 2025 Feature Update, it brings fresh activity options, faster satellite lock, and a host of fixes across the lineup. While all four devices share the same software version number, the Edge 1050 gets eight additional, device-specific enhancements.
In short: the headline 5Hz data recording, new Enduro/Downhill MTB profiles, Timing Gates, trail difficulty tracking, and ForkSight improvements are reserved for the Edge 1050. The Edge 540, 840, and 1040 still see meaningful gains like triathlon support, faster GPS acquisition via GPES, and numerous stability and usability fixes.

Why it matters
– More accurate GPS data: 5Hz recording on the Edge 1050 captures more points per second for tighter, more reliable ride traces—especially on fast descents and technical trails.
– Faster starts: GPES short-term ephemeris speeds up satellite lock so you can get rolling quicker.
– Smarter climbing and navigation: ClimbPro detection and resume have been refined, and Lock on Road improvements help prevent errant positioning.
– Broader training support: Triathlon events and workouts are now supported across all four devices.
Bottom line: If you ride with an Edge 1050, this is a substantial upgrade tailored for mountain bikers and precision tracking. Edge 540, 840, and 1040 users don’t get the marquee MTB features, but still benefit from faster GPS acquisition, triathlon support, and a raft of fixes that improve everyday reliability.
