How to update your Sony XAV-AX8100 firmware
Here is a simple and easy breakdown of how to update the firmware in your Sony Head-unit.
Step 1
- Download the appropriate file to a USB style thumb-drive from the website | Sony Support - XAV Series Head Units
- Move the files out of the downloaded folder directly onto the thumb-drive. The update can not be read if the files are in a folder or subfolder.
- It is important that the thumb-drive contains NO other files. The head-unit needs to detect just the firmware file.
Step 2
Gain access to the USB ports.
- If you installed the supplied USB adapter to retain your factory location, you're off to a good start.
- You may also unplug the USB from the back of the 8100 screen (located behind the right side of the screen behind the cover).
Step 3
Go to the main "HOME" screen of the head-unit by pushing the home button in the bottom left corner.
Step 4
Slide to the second set of icons on the touch screen.
Step 5
Push "SETTINGS" and go to "GENERAL"
Step 6
Scroll down to "FIRMWARE VERSION" using the down arrow on the right side of the screen.
Step 7
Connect the USB thumb-drive containing the firmware update to USB #1.
Step 8
Click "UPDATE"
Step 9
Follow the prompts on the screen.
Step 10
Once the update is complete remove the thumb-drive and reassemble any parts that were removed to gain access.
Notes:
- Your Sony head-unit may restart several times during the firmware update process, this is normal.
- You can verify that the update was completed by checking the firmware version shown in the menu.
