I sold my RX-V2700, but here are the latest firmware instructions and I have attached what I think is the last update (44). I never did update my unit, as it wipes out some of the settings and from what I read, it only fixed a few minor things. USE AT YOUR OWN RISK - DO YOUR OWN HOMEWORK!!! That said, I did obtain these instructions and the firmware file directly from Yamaha's website about 1 year ago.
