How to update
To update, simply follow these easy steps:
- Download the desired update version to the device you will use to perform the update.
- NAVCOMM With the device unpowered, press the bottom black button (just above the joystick) and connect the power (usually the ignition key).
- NAVCOMM PRO / RALLY PRO / RALLY LITE / RALLY LITE ALU With the device unpowered, push the lever forward (roadbook lever) and connect the power supply (usually via the ignition key).
- The LED will glow solid cyan. This indicates that the controller is in access point mode. You can release the button.
- Search for Wi-Fi networks from the device where the update file is saved. You will see the HESA network. Connect to it using the password HESAPARTS. Turn off your mobile data connection.
- Once connected, enter the address 192.168.1.1 in your browser.
- You will enter the update screen, where you can view the version installed on your device. For NAVCOMM, enter model (NAVCOMM) and password (NAVCOMM), both in uppercase. For NAVCOMMPRO, model (NAVCOMMPRO) and password (NAVCOMMPRO); for RALLYLITE, model (RALLYLITE) and password (RALLYLITE); for COPILOT, model (COPILOT) and password (COPILOT).
- Select the file you downloaded and press “update”.
- Wait for the update to complete 100%. It will take just a few seconds.
VERY IMPORTANT: Never update using a file that is not an official HESAPARTS file. Doing so may irreversibly damage the device.
Never attempt to update a model using the file from a different model.
