I want to add an aftermarket touch screen to my 06 Jeep Commander. I have seen multiple part numbers out there (either 1EH75XDVAE or 5JT12XDVAI). I'm not totally sure what the difference is, but one might be 07 vs 06 (those years the nav bezel is the same). Anyway, i have found online for 130 dollars, but was hoping someone had one for a better deal. Please let me know.
