It looks like I need to travel to the United States National Radio Quiet Zone in West Virginia to update the firmware in my headphones, and I don't think that's on the cards for several months so I hope the update isn't important.
Nice touch that they gave an example of a vehicle though, that really helps.
Maybe use a checksum Sony?
