Not related to the Rebel, but on the topic of updating buttons. Ram really needs to add physical buttons for seat heater/vents and steering wheel heater. I absolutely despise the fact that I've got to use the screen to turn the seat heaters on/off. Same goes for the steering wheel. Ford realized their mistake and at least brought a physical button for the heated steering wheel.
I don't understand how every truck manufacture can place huge screens in their trucks, and somehow still place physical buttons, and Ram can not. Slap the heated steering wheel button onto the steering wheel (where it arguably should have been to begin with), and give me 2 buttons on each side for heated/vented seats. There looks to be room at the top of the screen bezel, and if not extend the buttons a little further up on each side of the screen.
This, along with the buggy screen, are the two things that prevented me from buying the 12" screen. I was really surprised when the UC5 didn't address this.
