www.hyundai-forums.com/threads/getz-steering-wheel-controls-stereo.80772/well, i nailed it just today!
really happy with it. there is a slight lag after pressing the buttin but its not that bad.
I got the thing at a good price from the U.S. pretty quickly.
The '07 Getz (and probably others) have two wires, red and pink, that connect to the factory deck to control from the steering wheel, in a separate plug to the main wiring harness.
- The RED wire carries the info and must be attatched to the WHITE wire of the SWIJACK interface.
-The PINK wire must be connected to neg (-) ground.
The other SWIJACK connections are as follows...
-connect the red wire to 12v switched, or accessories. it does not need memory.
-connect the black to neg (-) ground.
THATS IT!! - all other wires must be tied off and insulated. the programming instructions are very clear. just make sure you use a compatable deck. i used Alpines 9883e from alberts perth, cheaper than ebay! Alpine decks 9881, 9883 and 9885 all have the 3.5mm plug at the back for use with this interface. I'm sure some of the older/cheaper models have the same. just be sure the plug is there at the back!
Any questions? if this isnt clear, post here and i'll fill you in.
Again, this was in an '07 getz. If your Factory Head unit also has 2 wires that plug in separately at the back, my guess is its exactly the same as mine. enjoy!!
