How to update your Sony 4000 or 6000 firmwareHere 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 3
Go to the main "HOME" screen of the head-unit by pushing the home button on the bottom left corner of the screen.
Step 4
Push "SETTINGS" and go to "SYSTEM"
Step 6
Scroll down to "SOFTWARE UPDATE" using the down arrow on the left side of the screen.

Click "UPDATE VIA FLASH DRIVE"
Step 9
Follow the prompts on the screen.
Step 10
Once the update is complete remove the thumb-drive.

Your Sony head-unit may restart several times during the firmware update process, this is normal.
