I've just found out that there was an officially sanctioned modified cup holder fascia designed to accept a switch of the sort found in the switch panel immediately above the cup holders.
Do not know about the 75 but certainly in early P6 parts manuals there were items shown that were never actually available - presumably planned and then cancelled.
Sounds interesting though - but a blank could be modified to take a switch
Paul just looking at a spare switch panel. If you cut the panel that the switches fit in to that could be stuck on the back of the fascia with the switch already in it........does mean there is a problem if you ever want to remove the switch. Or glue to actual switch to the back of the fascia - there is enough of a flange on it to do this.
Give Jake and or Lewis a prod. They will have seen one though in the wrong colour. What I don't know if they were ever officially produced, or just samples.
No luck with anything OEM on the OC but Dave Duotone has a home made one which you can see if he gets to another nano, and appears fairly easy to fabricate one
Planning is an unnatural process, much better to just get on with things, that way failure comes as a complete surprise instead of being preceeded by a period of worry and doubt
