Resetting GPS Tracking on Suunto 9 Peak

The Suunto 9 Peak is a robust multisport GPS device, but over time its tracking can become inaccurate or unresponsive. Resetting the GPS module can restore reliable performance, especially after firmware updates, long trips, or when the watch stops recording new activities. This guide walks you through every step of the process, from preparation to verification, ensuring that your watch’s GPS tracking is back to factory‑like precision.

Why Reset the GPS Module?

A GPS reset clears cached satellite data, removes any corrupted navigation files, and forces the device to rebuild its internal database. Common symptoms that signal a reset is needed include:

• The watch shows “Searching for satellite” for an extended period, even after the device has sat idle for days.
• Recorded distances are inconsistent or show gaps.
• The watch fails to start a new activity automatically.
• Firmware updates are incomplete or stuck.

Resetting the GPS does not erase personal data such as workouts, heart‑rate logs, or stored contacts. It merely refreshes the navigation core, so you can safely restore your data after the process.

Before You Begin: What You Need

1. A fully charged Suunto 9 Peak or a charger nearby.
2. A stable Wi‑Fi connection for firmware checks.
3. Your Suunto account credentials for backing up data (optional but recommended).
4. A spare pair of charging cables if your current cable is damaged.

Backing up data before a reset is a good habit. Use the Suunto Connect app to sync your activities to the cloud, or export them via USB to your computer. This guarantees that none of your historical information is lost during the procedure.

Step‑by‑Step Reset Process

1. Verify Firmware Status

A firmware glitch is a frequent cause of GPS stalls. To rule it out:

• Power on the watch.
• On the main screen, tap the left or right arrow until the “Settings” menu appears.
• Scroll to “System” → “Software.”
• Check if an update is available. If so, download and install it.
• After installation, reboot the device and test GPS functionality.

If the firmware is up‑to‑date and GPS still misbehaves, proceed to the reset steps.

2. Put the Watch into “Off” Mode

The GPS module needs to be powered down completely before resetting:

• Press and hold the power button until the power‑off screen flashes.
• Select “Power Off” from the menu.
• Wait for the watch to shut down completely.

3. Remove the Battery (Optional)

The Suunto 9 Peak’s battery is not user‑replaceable, but you can short‑circuit the power using a small screwdriver and a metal object. This is only necessary if the watch does not respond to the power‑off command:

1. Locate the tiny seam along the back of the case.
2. Carefully insert a flat‑head screwdriver to bridge the power contacts.
3. Hold the contacts together for 10 seconds, then release.

After the short, wait a few seconds and then power the watch normally.

4. Access the Hidden Reset Menu

Suunto hides the GPS reset behind a secret sequence:

• Turn the watch on and swipe left from the home screen.
• Tap the gear icon to enter “Settings.”
• Swipe left again until you reach the “Sensors” tab.
• Tap “Sensors” to open a list of all connected components.
• Scroll down to “GPS” and tap it.
• A prompt will appear: “Reset GPS module?” Confirm by selecting “Yes.”
• The device will flash a series of dots as it clears the cache and then reboot.

The GPS reset button is intentionally buried to avoid accidental resets. If the menu does not appear, make sure you have the latest firmware, as older versions may use a slightly different path.

5. Confirm the Reset

After reboot, the watch will automatically begin a new satellite acquisition:

• On the home screen, tap the “Activity” icon.
• Start a new run or hike.
• Watch the “Searching for satellite” indicator. Once it turns to “In View,” the GPS has re‑synchronised.

If the indicator remains stuck, power cycle the device again or try a different battery short‑circuit as in step 3.

Troubleshooting Common Issues

Advanced: Performing a Factory Reset

If GPS resetting fails and you suspect deeper software corruption, a full factory reset may be required. This will erase all user data, so back up beforehand.

1. Power off the watch.
2. Press and hold the power button while turning it on.
3. A prompt appears: “Factory Reset?” Confirm.
4. The watch reboots and guides you through the initial setup process.

After a factory reset, reinstall the latest firmware and then restore your data from backup. This should resolve any persistent GPS issues.

Quick Tips for Maintaining GPS Reliability

• Keep firmware current: Regular updates contain bug fixes and improved satellite handling.
• Avoid abrupt power cuts: Let the watch shut down properly to prevent corrupting internal memory.
• Use a protective case: Impact protection reduces the risk of hardware damage that can affect GPS.
• Check antenna clearance: Wear the watch over a clean, unburdened skin area; jewelry or tight straps can interfere with signal acquisition.
• Sync data daily: Frequent backups reduce the amount of data you risk losing in a reset.

FAQ

Q: Does resetting GPS erase my recorded workouts?
A: No. Only the navigation cache is cleared. Your activities remain intact.

Q: How long does the GPS reset process take?
A: Typically 2–3 minutes. If the watch takes longer than 5 minutes to lock, reposition to an open area.

Q: Can I reset GPS without powering off the watch?
A: The hidden reset menu requires the watch to be powered on, but you must first exit the GPS screen; the watch will still perform a short reboot during reset.

Q: My watch shows “No signal” even after reset.
A: Verify you are outdoors or in a location with clear sky view. If indoors, the GPS will not lock.

Q: Is there a risk of firmware corruption during the reset?
A: Very low if you follow the steps correctly and ensure a stable power supply.
