tofu Posted May 12, 2011 Share Posted May 12, 2011 Hello all, I just bought a new DVD Navi disc ver. 10.1 for my 02 SC430 after it updated put then it says no disc detected, and now my original disc I think it was ver. 2.1 when I put it back in it says Disck wrong version. Do you know how to down grade my Navi system so I could use the old disc? Or Can I force tthe system to update again? Thanx Quote Link to comment Share on other sites More sharing options...
Bly Posted July 30, 2012 Share Posted July 30, 2012 Was it a real Lexus update disc or a copy someone burned? I've been told that non original nav DVD's don't work well in older generation Lexus's Nav systems. They might work in a later year but not in a 2002. Assuming that's what you tried you might have to break down and buy a real one from Lexus. Quote Link to comment Share on other sites More sharing options...
tofu Posted August 3, 2012 Author Share Posted August 3, 2012 I bought the DVD from someone on Ebay and it is the real Lexus update. Now it doesn't read either one, old version or the new version neither works. Quote Link to comment Share on other sites More sharing options...
TexasMark Posted October 18, 2012 Share Posted October 18, 2012 Great avatar Lee! BTW, how can you be sure that the DVD is OEM? Is the disc id printed in the center of the disc marked? This would be in an area that a DVD burner could not read or write to. These areas generally contain manufacturer information and sometimes copyright etc...
