I have a 2006 and 2010 Prius both with a nav system. Could I technically copy the 2010 nav dvd and then have it work on my 2006 so to get the updated maps since I already own the 2010?
I was able to my suprise copy the 2010 navigation dvd and have the copy work in the 2010 car without issue. but of course the 2010 dvd is not reconized in the 2006 car
