I'm trying to figure out how to change the nav orientation on my 2009 CTS-V. I've fiddled with every option I can find, and have read the manual thoroughly. I'm trying to change the orientation from north always being "up" on the screen, to the direction I'm going always being up. Every navigation system I've ever used has had this option, but I can't seem to find it on the Cadillac. I assume I'm just being stupid somehow. Can someone please throw me a bone?
