2018 Ram Chassis Apple CarPlay Fix
If anyone is still have issues or cannot get there Apple CarPlay to work in the 2018 Ram chassis, Infotainment.com has made a custom module that will install in the dash. All you need to do is plug it into the back of the radio and the back of the 12v power plug. It also requires you to cut a place below the small drivers side cubby, but it is a simple install. They probably do not have it on their website yet. I have dealt with this for about a year and it was even at a Dodge dealership for about a month and they could not figure it out. It works and looks great. NO radio programming is needed.
