Press & hold the top button on the radio stick-control (behind wiper stick). the radio/cd LED lights should come on _ _ _ _ (on LH side) enter the 4 digit code. The roller control at behind control moves digits/channels etc up & down. The 2 finger triggers are for volume control. the button at the bottom is to change led /channel/track. after entering the 4 digit code press & hold button at the bottom of the control.
....a bit of practice should get you there.....if you get a loud " dooooh" & a blank led section you have pressed the wrong button LOL!!
