Just installed on a 2018 R1200GS Adventure, can't seem to get it to work without using the silver power button on the DVR unit, then it doesn't seem to want to turn off. Followed INNOVV recommendation to use the tail light wiring for the 'yellow' trigger (Red/Grey striped cable BMW), but I've seen elsewhere on this forum someone suggesting BMW 'pulses' the led's in the tail light - so the trigger may not work...??? Anyone know anything...???
