So I purchased a 2010 used Ram, and the owner installed a touchscreen RER which apparently has lockpick hard coded into it. No separate box installed. I took it out today to figure out how I have to install the OEM backup camera, but I don't see any empty spots to plug the camera into. If I take it to the dealer to install, I'm afraid they'll wipe it and I'll lose the lockpick access. Any suggestions? Attached is a pic of the back of the radio.

 

Also, while I'm at it, apparently there is no microphone so the uconnect won't work. Where can i get the microphone from and where does it plug into in the back of the radio? Like I said, I don't see any open spots, so I'm not sure.
