The wife's '02 X5 came with V18 installed. I was going to upgrade to V23, but I can't find a disk image - bmwnavigation.com is apparently down. I've got an image of V27.1 from http://www.megaupload.com/es/?d=9X481J1K - I never could get http://www.filefactory.com/?f39b3b to work.

Are there any downsides to using the V27.1 image on the MkIII? I've burned both a CD with V27.1 and another with the Key CD image. I'm ready to give it a try as long as it won't screw up the wife's ride...
