Ersin Stereo Wheel Button
I have an Ersin unit with GND, SW1 and SW2 , connecting GND to ground didn't work. After tips from bigdaddystew here, I connected GND wire to SW1 then wheel button worked.
My wiring explained: From Ersin radio Car stereo plug "BMW " GND & SW1 > blue/orange SW2 > blue/purple |
