Thank you both, so is the wiring there and all I really have to do it drop my headliner and replace the third brake light and it would show up on the infotainment system for the cargo bed. For the review mirror, i would have to buy the mirror and probably the wiring along with running that to the front. Is there any concern with having to flash or update my entertainment center? I do see that a company sells the package for the rearview mirror but not the cargo bed. I find that helpful when carrying things back there and not sure if items have shifted and potentially could fly out. Yes it has happened before.
@silveradosid who is WAMS? I am not familiar with that name.
