I jut bought a 2022 Ram 2500 Bighorn with the Safety Group. It did not come with Blind-Spot Detection. Dealer said that that group used to come with it, but with the chip shortage it currently is not. My truck is a 12-2021 build, and has the premium power tow mirrors. When I look in the mirror I can see the little triangle in the corner for the Blind-Spot light. My question is, can I, at a latter date, buy a module, plug it in, maybe tickle the BCM, and have the Blind-Spot work? Or, is it embedded in the BCM? Or? Thank you for any help.
