I've seen the thread, and videos, on enabling the Cargo camera on a 2018 Ram 1500, including the mystery surrounding waiting for the Camera icon to actually show up on the head unit (Uconnect 8.4). The same AlfaOBD options exist for 2020, so I started with the ones shown there: (a) Veh Config 1 - CHMSL Camera; (b) CBC Features - LED CHMSL Lamp Present. I did a hard reset by disconnecting and reconnecting power. I made several drive cycles over the next 24+ hours, and made sure the truck was locked and the key fob away from the vehicle between drives (a precaution based on Z Automotive instructions for their Jeep Wrangler front camera kit). I also made sure a camera was connected (to Uconnect pins 21 and 22) and powered during those drives (just in case it would refuse to enable unless it saw a video signal). The Cargo camera icon never showed up. I then went back into AlfaOBD and verified those changes read back as being on. I then scoured through the AlfaOBD options and found (c) Cust.Set.Menu 1 - CHMSL Line CSM Present (which I turned on) and (d) CBCConfig I/O - Stop Lamp CHMSL Feed Present - pin 31. That last one sounds intriguing because the pinout I have shows pin 31 as RVC Cam+. Does RVC stand for Rear View Camera? But the rear view camera comes in on the Red FACRA connector doesn't it? Is this maybe a no longer used input for non-Coax camera feeds? Beats me, but I left that setting off. In any event that didn't help and so I'm still stuck. I had no problem getting my Trailer Brake controller functions enabled but getting the Cargo Camera enabled has me beat. Has anyone managed this on the 5th gen?

Uconnect 8.4 (non-Nav version - God I hope that doesn't make a difference)
All these kinds of mods were soooo much easier on my 2010 Ram.

Unfortunately, the 8.4 no-nav radio for the 2019+ 1500 DT won’t display the cargo cam soft key.

Thanks so much for that Jimmy07. Crap, that was some hours wasted (a fair portion finding the proper pins for the Uconnect). Really long shot, but any chance it'll still display the camera and there is another way to switch the display (other than the missing on-screen icon)? I guess I can go back to the idea of hacking into the reverse camera feed but I'll need an analog to digital camera interface (I just found one based on Raspberry Pi). I guess I didn't mention it above but I'm wanting to be able to switch to the back camera of an RV. There's always the option of connecting to a WiFi reverse camera with my phone but that seems like such a shame when there's already a perfectly good display in the dash. Not to mention I already have a non-wireless camera set up. Sigh.
