Mark IV version 4.0 Options
2011-02-08 by Joan
Yamaha has posted some options for Mark IV Version 4.0 system update on its site: http://www.yamaha.com/yamahavgn/CDA/ContentDetail/Text_WithCatMenu_XC.html?CNTID=12177 They have listed a FTP site where you can find the Mark IV system update file folder and install notes to download to your computer. I used Safari to download from this site - (Firefox didn't work for me). I saved the files to my hard drive on my Mac.
