The top center of the dash is where you'll find the Ram's navigation unit and built-in audio system, which includes a Sirius satellite radio. Zone heat and A/C switches are visible just below the nav screen, with the 4WD controls are to the left of that.
The lower portion of the center dash houses seat heater switches and the power switch for the rear sliding window, which are flanked on either side by an auxiliary power plug and the cigarette lighter.
