Yes this does seem idiotic that a car costing $20k more gets the older nav but the cheaper M5 has the newer nav. My dealer ordered in a 2013 M5 and it has the new nav along with the ///M graphic on startup. Also has the connected drive animation as well. I have heard March 2013 for 6 series but maybe the M6 will be sooner. Lets hope. Mine should be arriving at the end of the week, curious what it has.
