Hey Guys, I have a base work truck 06 Dmax ally RC/LB. I also have 00 1500 base work truck with the 4.8 as the only option. The 06 has cc, ac and tow mirrors. Why is it that the 06 has a odo, hourmeter (that reads 78 hours with 114xxx miles), and a trip while the 00 1500 has a complete message center? My truck came without an owner manual so is there something I am missing???
