Has anybody managed to get the steering wheel controls to work successfully with an aftermarket stereo? I have just bought my 197, and decided since the radio reception is utterly terrible, I'd stick a DAB radio in there. With the added advantage of BT and USB for media playback. I've never bothered forking out the extra money for steering wheel controls in the past, but I like this car, so thought I'd give it a try. Car is a 2007 F1 Team, the yellow connector behind the radio has 5 pins, so I assume that means it is a CANBUS unit. I bought the Connects2 CTSRN005.2 and CTMULTILEAD.2 to achieve this. Having followed the instructions both in the packaging, and some youtube videos, I figured out that for my Kenwood KDC-BT720 DAB unit, I only needed the purple wires. Video guides suggested I snip the other two leads in the patch cable, so I did that. I then proceeded to wire everything up. The stereo worked fine, but the steering wheel controls didn't. I unhooked everything, and hooked it all up again, careful to make sure it was all in the correct order, and again, still nothing. Is it common for these not to work? Has anyone managed to get theirs to work?
