I brought a 2010 1500 laramie and it came with the REN radio and the dealer sold me a upgrade to the RER nav unit and rear view camera for the same price as factory installed. So the new RER nav unit came in today and I went get it installed with the rear view camera and now the I-Pod integration does not work with the dealer installed RER nav unit. The I-Pod soft button is not even on the screen when the I-pod is hooked up. And the stupid service tech is saying that he talked to mopar and they told him that the I-pod intergration will not work since the RER nav unit was not factory installed. It just don't make no since to me why it would work fine with the REN non-nav radio that came with the truck but it won't work with the RER nav radio. The wiring is already there in the glove box for the I-pod from the factory and it worked fine with the REN radio. Some please shed some light on this for me since the dealer service techs are no help.
