As far as I have read so far: the '05 needed a magnet to train the valve stems that came in the wheels when they changed position.
The '06 and up had the sensors in 3 wheelwells that combined with the ABS sensors to figure out which valve sender was transmitting from what position and retrained themselves.
If you already have the TPMS set-up in the Jeep, (They were required by Sept 2007, optional up to that point), then you ought to be ready.
Your part number says it will work with an '06 CRD.
My CRD Limited is an '06.
I bought a 56042756AJ, to replace the EVIC that just tells me that a tire is low along with the other data.
It's got the stereo controls on the steering wheel, fog lites and leather.... and whatever else is supposed to indicate that it's compatible with the upgrade option.
Some compatibility lists imply mine should work, mine doesn't specifically say CRD for '06, but the readouts lite up but show blanks for info where my standard/stock one showed temp and direction.
I read several how-to's that said that problems like this result from needing to have the computer reflashed by DC/J dealer mechanics, but I haven't yet managed to find out whether thats the same control module getting flashed that would be done by the one in this thread that is supposed to fix the dashboard CEL when the EGR is removed with the WEEKS induction elbow.
