Have you really checked to see what features you have? Push the button in your speedometer a few times to see whether you toggle through a compass, temperature reading, average gas mileage, etc.
Assuming you really don't have any of these items . . . .
At a minimum these would require a "computer flash," i.e., a dealer would have to reprogram your onboard computer to make those computations and display those features. There's been at least one post recently about somebody getting their computer "updated" at a dealer and viola! discovering new dash features.
What I don't know is whether you may also be missing some of the physical hardware. For example, if you don't actually have compass module, no amount of computer flashing will create one. The compass module, if your Jeep has one, would be located under your middle dash panel. You'll find a video showing how to remove this panel if you search this forum for "daystar panel," which is a separate product but requires you remove the middle dash panel to install it. That would be a simple check.
