Restart, update firmware, toggle GNSS settings, and set GPS recording to every second.
I’ve worked with GPS watches for years and helped many people fix how to fix epix gen 2 gps jumpy route tracking. This guide gives clear, tested steps you can apply now. You’ll learn quick checks, step-by-step fixes, advanced options, and settings that stop jumpy routes on the Epix Gen 2.
Why the Epix Gen 2 GPS shows jumpy route tracking
GPS jitter on the Epix Gen 2 often comes from software, satellite signal conditions, or settings. Urban canyons, tree cover, and battery-saving modes can cause the watch to interpolate or skip fixes. Many cases I’ve seen were solved by a firmware update or switching the GNSS mode and GPS recording to every second. If you want reliable tracks, you need to check settings, update software, and remove interference systematically.
Quick checklist to fix jumpy GPS on Epix Gen 2
Use this checklist first. It solves most problems quickly and safely.
• Restart your watch and phone, then re-pair the devices.
• Update watch firmware via Garmin Express or the Connect app.
• Set GPS recording to Every Second (not Smart).
• Change GNSS to GPS + Galileo or GPS + GLONASS.
• Turn off battery saver, UltraTrac, and power-saving sports modes.
If the checklist doesn’t fully resolve how to fix epix gen 2 gps jumpy route tracking, proceed to the step-by-step fixes below.
Step-by-step fixes that work every time
Follow these steps in order. I recommend testing after each change so you know what fixed the issue.
-
Restart and reconnect
• Power off the Epix Gen 2 for 30 seconds, then turn it on.
• Reboot your phone and re-open Garmin Connect.
• Re-pair Bluetooth if needed.
After a restart, test a short run to see if the route still jumps. -
Update firmware and apps
• Install the latest watch firmware via Garmin Express or Connect Mobile.
• Update the Garmin Connect app on your phone.
Firmware patches often fix GPS stability problems. Installing updates has fixed jumpy tracks in my tests. -
Set GPS recording to every second
• Go to Settings > System > GPS > GPS Recording and choose Every Second.
• Avoid Smart recording during troubleshooting.
Higher sample rates reduce interpolation that creates jumpy lines. -
Change GNSS settings
• Go to Settings > Sensors & Accessories > GPS > GNSS and select GPS + Galileo or GPS + GLONASS.
• If your Epix Gen 2 supports multi-band, try enabling it and compare.
Using multiple satellite constellations improves position fixes and reduces sudden jumps. -
Disable battery-saving features
• Turn off Battery Saver, UltraTrac, or any low-power sport profiles.
• Use standard performance mode while you test.
Power-saving modes lower GPS fix rate and can cause route breaks. -
Calibrate sensors and reset activity profiles
• Calibrate the compass and wrist sensors per the watch prompts.
• Recreate or reset any custom activity profiles that may have altered GPS sampling.
Sensor calibration has corrected odd positional spikes I encountered while testing. -
Remove physical interference
• Keep phones, magnets, and cases away from the watch during recording.
• Avoid carrying the watch under thick sleeves during a test.
Metal or devices with strong magnetic fields can interfere with accuracy. -
Clear activity and GPS cache (manual file removal)
• Connect the watch to a computer and back up files.
• Delete old activity files or corrupt GPS cache files if present.
Removing clutter fixed repeated jumpy routes for one client I helped. -
Factory reset as last resort
• Backup data, then perform a factory reset from Settings > System > Restore Defaults.
• Reinstall updates and reconfigure settings carefully.
Factory reset usually clears deep software faults causing persistent jumping.
If after these steps you still see problems, move on to advanced debugging options below focused on how to fix epix gen 2 gps jumpy route tracking.
Advanced fixes and diagnostics
When basic steps don’t help, use these advanced checks. They require more time but reveal root causes.
• Use Garmin’s GPS status tools
• Use Satellite info on the watch to confirm number of satellites and signal strength.
• Test from an open field to compare satellite counts.
Low satellite counts or weak SNR point to environmental causes rather than watch faults.
• Test with multiple sport profiles
• Create a simple running profile with every-second recording and no sensors.
• Test the profile on the same route and compare GPX output.
Eliminating external sensors isolates whether a paired device is injecting bad data.
• Export and analyze GPX files
• Export the activity and view the track on mapping software.
• Look for consistent spikes at the same points; this could indicate local interference.
GPX review helped me locate a building corner that caused GPS reflections in one case.
• Contact Garmin support and log a bug report
• If firmware seems to be at fault, submit logs and sample GPX files to Garmin.
• Support can sometimes provide beta firmware or confirm known issues.
Reporting the issue helps get official fixes for broader user benefit.
Best settings to improve route accuracy
Changing a few settings gives a big improvement in tracking quality.
• GPS Recording
• Set to Every Second for best accuracy and smoother routes.
• GNSS Mode
• Choose GPS + Galileo or GPS + GLONASS; try each and compare results.
• Performance vs Battery Saver
• Use Performance mode during activity. Turn off UltraTrac and battery saver.
• Sensors and Accessories
• Disable external sensors (like foot pods) while debugging. Remove them if they give bad cadence or speed inputs.
Applying these settings greatly reduces incidents of how to fix epix gen 2 gps jumpy route tracking in normal use.
Preventive maintenance and daily habits
Small habits prevent recurrence and keep your Epix Gen 2 accurate over time.
• Keep firmware updated regularly.
• Sync the watch daily with Garmin Connect to refresh satellite almanac data.
• Avoid storing watch near strong magnets or wireless chargers.
• Reboot the watch weekly if you use it daily for long activities.
These habits cut down the number of times you’ll need to troubleshoot how to fix epix gen 2 gps jumpy route tracking.
Troubleshooting workflow to find the root cause quickly
Use this short workflow to isolate the source of jumpy tracks.
- Reproduce the issue on a short route with every-second recording.
- Test in an open area to rule out local interference.
- Toggle GNSS modes and test again.
- Disable battery savers and external sensors.
- Update firmware and, if needed, perform a factory reset.
This method helped me and others diagnose the cause in under an hour in most cases.
Frequently Asked Questions of how to fix epix gen 2 gps jumpy route tracking
Why does my Epix Gen 2 track jump around?
Jumps usually come from low satellite visibility, power-saving modes, or firmware bugs. Changing GNSS settings and setting GPS recording to every second often fixes the problem.
Will a factory reset fix jumpy GPS on the Epix Gen 2?
A factory reset can remove corrupt settings or files that cause persistent GPS errors. Use it only after backing up data and trying all other fixes.
How does switching GNSS options help?
Using multiple constellations increases satellite visibility and reduces sudden position errors. Try GPS + Galileo or GPS + GLONASS to see which gives better results for your area.
Does GPS recording set to Smart cause jumpy routes?
Smart recording saves battery by reducing sampling and can create jagged or jumpy tracks on complex routes. Set GPS Recording to Every Second for best accuracy.
Can environmental factors cause jumpy GPS?
Yes. Tall buildings, dense trees, and reflective surfaces can cause multipath errors that make tracks jump. Test in open areas to confirm if the environment is the issue.
Conclusion
You can stop jumpy routes on your Epix Gen 2 by following a clear, stepwise approach: restart and update, set GPS recording to every second, change GNSS modes, disable battery savers, and test in open areas. Use the advanced diagnostics and factory reset only if simpler fixes fail. Try the checklist and workflow in this guide, then run a short test ride or run to confirm improved tracking. If the issue persists, submit logs to support or leave a comment below describing your symptoms so others can help.
