I GOT A D1 AND THE NAVI CD IS FROM 05, WHERE AND HOW CAN I FIND A NEW ONE. THANKS

IS THERE A CHEAPER WAY OF GETTING IT?

you can try ebay and search CNDV-80MT . most of them are copies looks like, or you can look around on the forum. there are lots of ways to get them., if you live near someone on the forum maybe they could get you a set. do you have a dual layer dvd burner? some dual layer dvd's??
