Am I correct in thinking that a pulsar with no factory fitted 360 or reversing camera (2015) can NOT have the steering wheel controls function with a Chinese android aftermarket head unit ? - it came with 2 canbus and 3 harnesses - 1 fits and works , 1 has the 2 connectors but one of them is too small but works when fitted , and the 3rd basic one has no canbus and not 1 white plug but works pretty much the same except for spatial adjustment ( fixed as centre for sound )
