1. Turn off the Humminbird GPS.
2. Remove the SD card.
3. Restart the unit.
4. Check GPS signal.

If the signal improves, inspect the SD card.

10. Reset Humminbird GPS Settings

Incorrect settings may affect GPS performance.

Before resetting:

• Backup waypoints.
• Save routes.
• Export tracks.

Then:

1. Open settings.
2. Select restore defaults.
3. Confirm the reset.
4. Restart the device.

Fix Humminbird GPS Signal Loss After Update

If signal problems started after an update:

Try:

• Restarting the GPS unit.
• Checking GPS source settings.
• Removing and reinserting the SD card.
• Confirming update compatibility.
• Reinstalling the software update.

Fix Humminbird GPS Weak Signal

If the GPS signal is weak:

Check:

• Antenna location
