Where did you buy the 2004 DVD W41? Are you sure it's an OEM DVD?
Yes, it is an original DVD and was given to me by a friend who manages a large body shop. It is in excellent condition. Thanks for your prompt reply. Got any ideas? After trying it the W-41 D, I put the original one back it and it works fine.
Step Hen...thanks so much for you reply. I do not know what generation my 02 Lexus has...the disk I have is an original and it says version 4.1. The text is a green in color, but there is no text that tells what the Gen is.
