Garmin Beta 18.29 is rolling out to six watches: Forerunner 70, Forerunner 170, Forerunner 570, Forerunner 970, Venu X1 and vívoactive 6. The maintenance release fixes alarm quiet-start behavior across the group. On four supported variants, it also prevents voice alerts from playing when silent mode is enabled.
What Garmin Beta 18.29 changes
Alarm quiet starts are fixed on all six models
The primary correction addresses alarms that did not honor a quiet start. Garmin’s quiet-start setting is intended to let an alarm begin without an audible alert, but the behavior was unreliable. The fix applies to the Forerunner 70, Forerunner 170, Forerunner 570, Forerunner 970, Venu X1 and vívoactive 6.
Silent-mode voice alerts are corrected on selected watches
Beta 18.29 also changes how voice alerts behave while the watch is in silent mode. The improvement is reported for the Forerunner 570, Forerunner 970, Venu X1 and Forerunner 170 Music. Voice prompts should no longer sound in silent mode on those models.

Other fixes are not itemized
Garmin describes the release as including multiple fixes for other “minor issues,” but neither Garmin nor the reported rollout provides a complete bug list. Those unspecified corrections should not be treated as confirmed fixes for any particular symptom.
Eligible watches at a glance
| Watch | Beta 18.29 eligibility | Silent-mode voice-alert suppression | Important qualification |
|---|---|---|---|
| Forerunner 70 | Yes | No | Receives the alarm quiet-start fix only among the changes described here. |
| Forerunner 170 | Yes | Music/Wi-Fi model only | The non-Wi-Fi version does not receive the voice-alert behavior change. |
| Forerunner 570 | Yes | Yes | Receives both documented behavior fixes. |
| Forerunner 970 | Yes | Yes | The Garmin Forerunner 970 smartwatch is included in this maintenance rollout. |
| Venu X1 | Yes | Yes | Receives both documented behavior fixes. |
| vívoactive 6 | Yes | No | Receives the alarm quiet-start fix; voice alerts remain outside this change. |
Why voice alerts may still sound in silent mode
Silent mode does not guarantee the same behavior on every Garmin model. Beta 18.29 changes voice-alert handling only on the Forerunner 570, Forerunner 970, Venu X1 and Forerunner 170 Music. If you use a Forerunner 70, vívoactive 6 or non-Wi-Fi Forerunner 170, continued voice prompts are consistent with the documented model limitation rather than evidence that the update failed.

Rollout timing can also vary. A watch may show the new version later than another eligible model, depending on delivery through Garmin’s update channels.
How to install the update
Garmin supports three delivery routes. Keep the watch charged and connected during installation; the exact menu wording can vary by model and software state.

- Automatic device updates: Enable automatic updates in the watch’s system/software settings. When Garmin makes Beta 18.29 available to your device, it can download and install during an eligible charging or sync period.
- Garmin Connect: Pair the watch with the Garmin Connect mobile app, sync it, and allow the app to deliver any offered software update. Keep Bluetooth enabled and the watch near the phone until the installation completes.
- Garmin Express: Connect the watch to a computer running Garmin Express, select the device, and install the software package shown for it. Do not disconnect the watch while the update is being transferred or applied.
After installation, check the watch’s software-information screen and test the setting that matters to you: create a quiet-start alarm, enable silent mode, and trigger a supported voice-alert scenario. A missing update prompt usually means the rollout has not reached that device yet, the watch is not one of the six listed models, or the installed variant is excluded from a model-specific change.
How this differs from Garmin’s larger 2026 feature release
Garmin’s February 24, 2026 newsroom announcement described a broader software release for compatible devices including the Forerunner 970, Forerunner 570, Venu X1 and vívoactive 6, as well as other watches. That release introduced capabilities such as expanded gear tracking, gear collections and a gear database, course planning, live sports scores, Garmin Fitness Coach, mixed-session activity tracking, Varia voice alerts, sleep alignment and lifestyle logging.
Rank #4
- Make a bold statement with this rugged GPS smartwatch, featuring a 0.9” display with solar charging lens and unlimited battery life with solar charging (assumes all-day wear with 3 hours per day outside in 50,000 lux conditions)
- Engineered with a supertough 45 mm fiber-reinforced polymer case and metal-reinforced bezel
- Built-in LED flashlight with variable intensities and strobe modes gives you greater visibility in the outdoors and provides convenient illumination when you need it
- Know your body better with health monitoring features, including wrist-based heart rate, advanced sleep monitoring, Pulse Ox and more (this is not a medical device, and data presented is intended to be a close estimation of metrics tracked; Pulse Ox not available in all countries)
- Navigate confidently with a 3-axis compass, barometric altimeter and multi-band GPS with SatIQ technology, which delivers superior positioning while also optimizing battery life
Those capabilities are separate from the narrower Beta 18.29 maintenance update. A watch can be eligible for the feature release yet receive individual fixes at a different time, and feature availability can vary by model and connectivity. Garmin said on February 24 that compatible devices had started receiving the free software updates; the Beta 18.29 report was published September 4, 2026 and updated October 5, 2026.

What about Venu 4?
Venu 4 was not included in the reported Beta 18.29 rollout. At the time of the October 5 update, it remained on Beta 18.27. That status does not establish whether a later Venu 4 release will contain the same fixes, so owners should rely on the version offered through Garmin’s official update channels rather than assume parity with the six eligible watches.
