How to install CVP700 series USA Edition upgrade on CVP809?

[jaypatriot]

Just got my CVP-809 and planning to install the
C:\Users\jlato\Downloads\Yamaha Music\CVP700_Series_USA_Edition_Upgrade(2)
The file is on my laptop. I need instructions on how to transfer the files over to the CVP809 using a USB drive.

There is a CVP705 and CVP709 folder. No CVP809 folder
There are 701, 705, 709 .bup files.
Which one do I install on my CVP809.?
Where are the written instructions on how to do that?
Very confusing. I need help.
