I took apart GBMINI#6’s center stack today, to install a new toggle switch panel:
Thus, no more empty toggle positions (although the front/rear fog switches currently don’t work); and I now once again have somewhere to install the (unique?) chrome toggle rings (which I removed from GBMINI#3 before I sold it) – of course, I took the opportunity to install an auto-up windows MINI circuit (another benefit of not owning an R56!).
I also checked the AUX input cable to the back of the radio, it seemed to be properly installed – but it still doesn’t work! 😦
