I have a WORKING nav system on CD #9 (South East) ..... IF, I try any other CD from my library (CD #1 through #11), the NAV system does not recognize any of those cds, but I can put back #9 and it works in my home area ......

Suggestions from you experts are highly appreciated!!!!!

 

UPDATE: I have received my STAR DVD and there are some reported issues about having a certain part number of NAV system that will ONLY runsome LATER versions of NAV DVDs!

I don't have possession of the car, but will update post if that is the case, AS I KNOW THAT I do have a few (not sure if more than 1) version of DVD's .... maybe I only have correct #9 and all others are earlier ..... that is what I am hoping anyway ....
