Directories of Firmware
The folders are cryptically named and they are only really helpful if the vendor has pointed you in the direction of where to find the file you need. It is very risky (risk of permanently making it not work ever again) to the head unit if you flash the wrong firmware.
Wrong Firmware
Don’t randomly flash random firmware. Even if you think it many be right, it probably is not. Best to seek advice from the vendor or the experts at the https://www.xda-developers.com/ forum for android based car radios before any flash. Be sure you know why you need to flash. Some updates bring improvements but at a cost of disabling other features. Be sure you know what you will loose as you can’t roll back a flash.
