Hi All, I just replaced my C30 shifter blind. The magnet is in the the right place and the circuit board is undamaged. The vehicle only registers D,P, N, R. it won't show 1,2,3 etc if I move the shift to manual and it does not respond to + -. It was working before on the original blind before that broke. Am wondering if the magnet has a polarity and perhaps the replacement part from China has magnet inserted the wrong way.
Any advice appreciated.
