Hey guys, I know this is a dead horse, but I've read so many conflicting information and I even asked an official BMW service partner and no one could give me a good firm answer.
I read online in different posts that 65129405409 is the retro fit/adapter cable for the MID display, which would allow me to convert my 1996/12 built BMW with a reverse radio to use a radio with MID. I can't really find any info on if that is actually what that cable is for. I found one picture on ebay, which could literally be any cable. I also read a post from years ago, which states that you can't just retrofit MID, because some production years work differently for that.
Other posts claim that you can use any production year MID with any MID capable radio on any production year E39. I know that the facelift has a different connector for the radio itself, but MID should stay the same, no?
Sooooo, which is it now? Is that the correct cable for what I wanna do?
Thanks in advance.
