I would like to install an iPhone 5 snap in accessory. I currently have the 6NH option. Can a BMW dealer upgrade me to 6NS simply?
I have seen it done before by coding the vehicle in the aftermarket world. The dealer may be able to do it as well can't remember if any hardware has to be changed though. I would have your dealer talk with there RTE on the subject since he is the only one that can change vehicle coding on that level.
