Encountering a glitch on your Garmin Edge 800 can be frustrating, especially when the device freezes, behaves erratically, or fails to respond to normal inputs. This is where the need to know how to reset Garmin Edge 800 becomes critical, offering a straightforward solution to restore its functionality. A reset clears temporary memory and stops errant processes, effectively rebooting the system to a stable state.
Before diving into the steps, it is essential to understand the two distinct methods available: a soft reset and a hard reset. The soft reset is the first line of defense, acting like a standard reboot for your cycling computer. Conversely, the hard reset, often referred to as a factory reset, is a more drastic measure that wipes all user data and settings, returning the device to its original factory state. Choosing the correct method depends entirely on the severity of the issue you are facing.
Performing a Soft Reset
A soft reset is the recommended initial troubleshooting step for everyday malfunctions. This process is safe, quick, and non-destructive, meaning your maps, routes, and activity data remain completely intact. It clears the cache and refreshes the operating system, resolving minor software conflicts without any risk to your personal configurations.

Step-by-Step Soft Reset Guide
To perform a soft reset, you need to locate the tiny recessed reset button on the back of the device. Because the Edge 800 is designed for rigorous outdoor use, this button is hidden to prevent accidental presses. Follow these steps carefully to execute the reset:
- Ensure the device is powered off completely before you begin.
- Locate the reset button on the back panel of the Garmin Edge 800.
- Using a paperclip or a SIM ejector tool, gently press and hold the button.
- While holding the button, use the power button to turn the unit back on.
- Continue holding the reset button until the Garmin logo appears on the screen, then release.
Executing a Hard Reset
When a soft reset fails to resolve the issue, or if the device is completely unresponsive, a hard reset becomes necessary. This procedure is the digital equivalent of a clean slate, erasing every piece of user data, including saved routes, profiles, settings, and connected device integrations. You should only proceed with this method if you are prepared to reconfigure the device from scratch.
Precautions and Data Warnings
Before initiating a factory reset, backing up your data is highly recommended if the device can still be powered on. Garmin does not offer cloud backup for the Edge 800, so data recovery after a hard reset is often impossible. If the screen is completely black, however, you can still perform the reset to restore basic functionality, accepting that the previous data is gone.

Factory Reset Procedure
The hard reset utilizes the same physical button combination as the soft reset, but the trigger for the system wipe happens during the boot process. To execute a factory reset, follow these steps:
- Turn the power switch to the Off position.
- Press and hold the Reset button on the back of the unit.
- While continuing to hold the Reset button, turn the power switch to the On position.
- Keep holding the Reset button for approximately 15 seconds after the screen lights up.
- Release the button when the format screen appears or when the device begins to reboot.
Understanding the Boot Sequence
Whether you are performing a soft or hard reset, the physical process is identical; the difference lies in the timing of when you release the button. Observing the boot sequence is crucial for ensuring the reset type takes effect correctly. A standard reboot will load the operating system normally, while a factory reset will usually display a menu or format screen if the button is held long enough.
For optimal results, ensure the battery is sufficiently charged. A low battery can cause the reset process to fail mid-operation, potentially leading to a bricked device that requires service. Patience is key during this procedure; holding the button for the full duration ensures the command is registered by the firmware.
