Upgrade the firmware

Upgrading the firmware is a pretty straight forward process, and it does not require any special tools or procedures apart from the official way, regardless of the Media Nav generation.

This guide applies only to firmware versions newer than the one currently installed. In order to downgrade to an older version, for first and second generation Media Nav units (MN1 & MN2), see Downgrade the firmware (MN1 & MN2).

Guide

Note: Most versions are installed using only one file. Yet, for versions 4.0.2, 4.0.3, 4.0.5 & 5.2.7, two parts are required, so follow the two-part installation guide below.

Prerequisites:
– a tablet, laptop or desktop equipped with an USB port
– empty USB flash drive, FAT32 formatted, max. 32 GB capacity

One-part installation guide

Step 1. Download the firmware you want to install from the Firmwares pages, according to your Media Nav generation and your current firmware version. The firmware you download must be a newer version.

Step 2. Extract the ZIP archive and put the file upgrade.lgu in the root of your USB flash drive – the file should be the first to be seen upon accessing the flash drive.

Step 3. Start the car engine and wait for the Media Nav unit to boot. Do not turn off the engine until the update is complete.

Step 4. Insert the flash drive in the USB port and press Upgrade on the update notice. If no notice appears, go to Settings > System > System version and press Upgrade once the notice is shown.

Step 5. The Media Nav will reboot and start the installation of the new firmware. After the installation is complete, the unit will reboot once again and go to the main interface. The engine can be turned off at this point.
