I am new to this and am trying to help my wife out with her piano. We have a Yamaha Clavinova CVP-309GP. I have downloaded the firmware updates their website provides and am trying to find a way to install them. The docs that go with the update just point to another website that does not actually seem to have any information about the install process.

As the piano seems to be EXTREMELY picky about hardware it can talk to I have not even got the network connection going so I am relying on the usb connection to do this.

Any helpful tips would be greatly appreciated.
