What's New in Version 9.05?

Premium Mapping Fix

  • Fixed an issue where green contour elevation lines would not appear correctly on some courses when using premium mapping.

Why This Update Matters

More Accurate Course Visualization

The Approach S50 is built around a richer golf-map experience. Green contour lines are useful when judging slope and planning shots around the green, so fixing their display helps preserve the value of premium mapping.

Focused Stable Update

Version 9.05 does not list a large set of feature changes. Instead, it targets one specific visual issue that can matter during a round on affected courses.

Staged Release

Garmin is rolling this update out to 20% of users first. If you do not see it immediately, the staged rollout may not have reached your watch yet.

Installation Instructions

The update may arrive automatically through Garmin Connect when your watch is paired with your phone. You can also check manually:

  1. Open Settings on the watch
  2. Go to System
  3. Select Software Update
  4. Follow the on-screen prompts if Version 9.05 is available

Garmin Express can also be used by connecting the watch to a computer.

Important Notes

  • The rollout is currently at 20%, so update availability may vary.
  • Keep the watch charged before installing firmware updates.
  • Course data, scorecards, and round history should remain intact after the update.

Conclusion

Garmin Approach S50 Software Version 9.05 is a focused stable firmware update for golfers who use premium mapping. The green contour elevation-line fix improves map reliability on affected courses and is worth installing once it reaches your watch.
