Default JB4 installed with OBD2 cable, cannot check map with BC button - 06-30-2020, 01:15 PM

Hi, I recently installed my JB4(BMS Data Cable) on my 2013 n20 328i EWG. I know all the connections including the OBD2 port are secure. The car definitely feels stronger but I donít know if itís the JB4 or the new ******** since I also did the ******** at the same time.
My issue is that I canít check my map setting with the BC button hold method; nothing happens with no blinker lights or anything. 1. What might be the issue of the steering wheel controls not working?
