I bought a new rear entertainment remote for my 2012 F02 (65129231373) and can not figure out how to get it to work. The local dealership I got it from said it should just work with no programming. I called another dealership and they think it needs programmed but don't know how to do it. I have a copy of ISTA if I need to use it to program, just need some instructions if that is what need to be done. Anybody have a clue?
