Einleitung

This guide provides step-by-step instructions to update the firmware of your Mitsubishi Hands Free Module (HFM). By keeping your HFM's firmware up to date, you ensure optimal performance, compatibility with new devices, and access to the latest features.

Werkzeuge

Schritt 1

Enter the Service Menu by pressing and holding the SETTINGS and MAP-Buttons for 4 seconds.

Schritt 2

Enter the Service Menu by pressing and holding the INFO/SET and SEEK-Buttons for 4 seconds.

Schritt 3

Press on Hands Free Module.
While the Hands Free Module is in diagnosis mode, the sound input to the microphone unit is output directly through the speaker.
Check the Parts Number.
We'll need this later when downloading the Firmware file.
Check the Version Number.
If the Version Number is 19.00.000 you already have the last available Firmware installed and don't need to do anything.

Schritt 4

You can download the firmware files here: Version 19.0.0 (Europe) and Version 19.0.0 (Japan and North America).
Check if the Firmware Version works with your device.
Download the Firmware for your device.
Press on SHOW ALL.
Download update.package.

Schritt 5

The flash drive needs to be formatted to FAT32 and should not be larger than 16GB. Additionally the MMCS can be a bit picky and might not accept all flash drives. If it can't read your flash drive, just try a different one.
Copy the update.package file to the root directory of the USB flash drive.

Schritt 6

Insert the USB flash drive into one of the USB ports in your car.
You can usually find a USB port inside the center console or below the head unit.

Schritt 7

Re-enter the Hands Free Module-Section of the Service Menu.
Press on the S/W Update-button.
If there is no S/W Update-button it means that the head unit didn't detect a valid file on the flash drive. This either means that you already have a version newer than the firmware file installed (as is the case for me), an incompatible firmware file, or that the system can't read the flash drive.

Schritt 8

Enter your Security PIN.
If you don't have one set you can just enter 1234.
If you have forgotten you Security PIN, you can forcibly remove it by pressing the Unlock-Button in the Hands Free Module-Section of the Service Menu.

Schritt 9

Wait for the update to finish. This may take some time, don't worry if the progress bar stays at 0% for some time.
Do not remove the flash drive or turn off the car while the update is running!
If the update fails and the warning message states that you should make sure that the USB port is properly powered, you can just reboot the head unit and try again.
