I am looking at putting in a new head unit into my 2011 Hyundai Getz....the problem is I can not seem to track down a harness that will allow me to hook up a new head unit to the steering wheel controls. Has anyone any ideas of where to track one down. I have done lots of searching online / ebay etc but have had no luck. People have told me that you can not buy them for that model car. Is this correct? Can I just re-wire it myself?

If you have any ideas re head units with bluetooth for under $400 happy to take advice as well.

Thanks.
