You got two sets of NAV CDs radmanly?? Interestingly, the West region CD used to generate the ISO image is the black one which was in the NAV unit of my car when I got it. It has the A 193 827 02 59 part number on it. The East region disc was a copy sent to me by forum member crossfirefun and, while I can't say for sure that the original was a black disc, I assume it was. The copy works fine in my NAV unit.

What bothers me now is that you are not able to use the discs burned from these ISO images, yet apparently ShawnQ can. Unless Shawn has not actually tested them in his NAV unit yet.

That is something I'd like more feedback on - whether or not the discs burned from the ISO images are useable in the NAV units. A simple download and burn is not the true test!!! They work for me, but that's not what's important - I want them to work for YOU!
