Many of us with a Stealth Hitch install will really only use it for carrying bikes but would also like to have the iDrive Trailer Mode available to us so that the sensors on the back and sides of the car are set to "stop annoying me" mode.
Mjbmw1 would you happen to know if installing the controller without the external harness would achieve this please? I know it seems a waste, but I'd be super happy with this setup for the short term until I can get the external harness installed too.
