Adding factory mileage gauge to my Sonata

When I bought my '09 Sonata new, there was an option that consisted of a mileage computer and I think, power seats.

Don't miss the power seats a bit, but, it would be nice to turn on the mileage computer. I say "turn on" because I am fairly sure that all the hardware already exists and it is a matter of modifying the computer gadgetry. I saw this feature on a car at the dealer. All the mpg info lived in the same display as the odometer.

Does anyone have any experience with this? Is it possible to go to a Hyundai dealer and have them turn this feature on? I could just go out and buy a scangauge, but, I like the idea of having something already built in.
