I have had my 12 CS for about a week now and I am extremely pleased with it. One thing though in the demo I drove when I ordered iit was that I could swear that it had the speed limit of whatever road you were on show up on the Multi Function Display navi screen and I remember thinking how helpful that was in reminding you of what the speed limit was on the road that you were currently traveling on. Well I have searched and I cannot find where to enable that particular function.

Was I dreaming this or am I missing something?

 

You were not dreaming. I have it configured this way and its really a great option. You have to set it in the "top line" in the settings menu. Traveling this weekend (without CS), but will check steps when I get home and post them.

 

You remember correctly and WFBlue is correct it will appear on the top line of the multi-purpose display. In the MP display select vehicle>settings>display>PCM display and then check the PCM information you want displayed, which includes Speed Limit. It works very well and changes the speed limit sign in the display as you are turning a corner from one level of speed limit to another. I have found no delay. Before I complete the turn the new speed limit is in the display. Very cool and useful.
