The_Ox Posted April 18, 2009 Share Posted April 18, 2009 I searched but could not find out how to upgrade my Gs from 5.1 to 7.1 so thats my question. I put the 7.1 in and the nav says searching disc or something like that. Where can I get the info to do this upgrade? Thanks Quote Link to comment Share on other sites More sharing options...

If the new disc you bought is anything but -3304X then it will not work. Quote Link to comment Share on other sites More sharing options...
