Hi Guys, I apologise if this is already posted in here somewhere but I cant seem to find it. I have a 2011 Black Edition 140 STronic. I am looking for information on what I need to retrofit an RNS-E e.g. Programming, coding, unit version, etc. Also I eventually want to get an engine remap any advice on the best place to go that would be great. Thanks happy to be on the site.
