Hi i just installed a Kenwood DDX512 into my 04 G35 coupe. I got the double din combo kit off ebay which had everything with it, and it definitely looks great. I have a quick question though... what exactly would i need, or what would i need to do the make the steering wheel controls work? thanks

 

You need the PAC-JACK.

 

thanks for the quick response. so it looks like the pac jack is kinda pricey for what it actually is and does... any other way the could configure it?
