I recently got a PX6 for my 2017 RAM 3500 - all works great but I can't figure out how to access the OEM Cargo Cam. With the stock radio I'd put it into Reverse and there was a button that let me toggle between the Cargo Cam and my normal Reverse Cam. With the new unit, I don't have that same button and can't find any way to switch it over.
I took a look at the wiring and I don't see any separate cables for 2 cameras - there is just the one RCA coming into the back so I'm a little unsure of how the stock solution worked. I'm assuming that when you pressed the button it worked as a switch to toggle between the two cameras but I'm really not certain. I'm open to splicing into the original harness > RCA if needed but I haven't been able to find any descriptive wiring diagrams that would show me what pins I'd need to access.
Anyone have any ideas? Genuinely appreciate any help!
