I have just been informed that Lexus no longer supports the navigation map dvd for the 2003 lx470. The navigation system is therefore no longer functional. Does anyone have any further information or any ideas?

 

Our 2003 still had the original Navi DVD so I went to Lexus and asked the Parts Dept. for the newest version. They said that 2013 was the newest one you can get so I bought it because it was still 10 years newer than what was in there! Here is the part number if you want.
