I have a 2002 CL500 and recently moved to the northwest, my friend let me borrow his Navtech CD 2 (Northwest Area) he has a BMW745, anyway when i inserted the CD on the Navi it tells me that it needs a DX Navigation CD, the CD i inserted is original NavTech CD #2 Northwest area, is there a different on the CD's? how do i know if the cd is DX or not as i need to purchase one now that live in Seattle, thanks a lot, by the way my CD #7 works fine

 

BMW's navigation CD will not work on your CL.
