Hmmm, so, is it now installed? Are you driving the car with it? If so, what do you now think?
I just got mine done today. A 2016 75D, AP1. I will summarize it by just saying, it feels like my wife 3 and my friends Y. For 2k usd or 3k cad, and having a more modern experience, it is worthwhile. I think I can keep this car a few years longer with this touch.
