After purchasing a Sony Navitus I realize that I did not research it as much as I thought because I cannot find any information on how to custom program it. If anyone is familiar with this unit I would appreciate the help. I can only find ways to teach it the generic codes not anywhere to download codes such as the harmony unit website offers. In my quest for information I also found out how little help Sony can be. I am trying to set up each screen and while I can find a code that will do some basic functions such as on/off. I can't find a way to understand how to emulate each function other than those. Is there any site to download complete codes like harmony does or a way to get the remote to learn them that I am missing?
