    Hey guys. I'm looking for some clarification on adding a Cargo Cam on my 2014 Laramie 1500 CC. I have the 8.4 w/ Nav and tailgate cam w/ rear park sense. I'm trying to read other posts/replies about this but am still confused. I purchased a cargo cam light today and am awaiting its arrival.

    So just trying to get ready, I know I'll need the harness and already have AlphaOBD to activate it. But what else am I needing? And what pins do I need to replace/move? Should I go looking in the truck behind the radio and the brake light to find out?

    Also, how will I be able to activate the camera? Will it be along the bottom of my radio or how does that work?

    I can supply the VIN if needed to help.

    Thanks for the help!

    After checking my radio this morning I'm in version 14. 05.x so is it possible to update to a certain version?

    Wait so can I only use 17.11.x or Can I also use 18.45.x? Or does the 18.45.x have to be updated from the 17.11.x?

    Did you figure this out?
    I have the same unit and would like to add the cargo cam. Where did you get the camera and harness from?

    I'm trying to figure out the same thing for my 14 Sport. I can tell you that on 18.45.x after enabling CHMSL camera options with AlphaOBD, I get the "cargo cam" button, however when I click it then it only shows my existing tailgate camera with no option to switch.
    All videos I've seen show ability to switch between the two (though only get a blue screen when the camera is not hooked up).
    Going to look into trying to downgrade my RA4 and see what happens

    On the 13 to 15 radios they need to have been updated to the 17:11:07 firmware in order for the cargo cam and backup cam to both appear on the radio screen. All 13 to 15 trucks originally equipped with the 8.4 radio and the cargo cam displayed the backup camera in the rear view mirror and the cargo cam on radio screen. The 16 and 17 trucks show both on the radio. When the 17:11:07 version firmware was released it had a glitch that allowed the 13 to 15 radios to display them both on the radio screen like the 16 and up trucks. This was corrected with the next update 17:43:××. I have heard that if you update from the 17:11:07 directly to the 18:45:01 you will still keep the function but I have no first hand knowledge. If you upgraded to 18:45:01 from any firmware version other than 17:11:07 your most likely not going to be able to have them both display on the radio. I don't recommend going down in firmware versions. I have seen people brick radios when doing this. If you are unable to correct the issue you can install a 16 or 17 8.4 radio your backup cam/cargo cam should both display on the radio as long as you have enabled all the correct codes in your BCM.
