which nav disc?

[lossimo]

Hi all!I am confused as to which version nav disc I would need for my G.When I bought it last month,it did not have the disc.The dealer said it would need to get one for me(funny how the ad for the car showed the nav working with steeets showing?!?!?!).Well one month later the dealer sent me version 7.2,a light purple/violet colored disc.I tried 5 times to load it,but it kept showing disc eror.Is there something I need to do to prep the car for the disc or did the dealer swipe the wrong disc from the auction??

All my searches turned up nil.

thanks in advance!
