In the instructions we detail where you have to connect the high speed CAN wires at the junction connector rather than the OBD2 for the 2018-up model trucks. Once that is connected you should have all your gauges and other information on the radio. We do not source video for the rear camera when it goes to the rearview mirror, only if it was displayed on the factory radio screen. You would need to hardwire the view connection from your mirror to the new radio.

Make sure that you have the harness configured as we show in the guide. The black 2 pin connector that goes to the CAN wires should be plugged into the black 2 pin on the CH3 harness, not the red

nothing will plug into the red connector, just leave it disconnected.

unfortunately CarPlay and Android Auto require a large amount of data transfer and because of the distance away the USB is they do not work. You can still use the uRam for other USB duties but just not for CarPlay or Android Auto.
