Any info on your head unit, tapping in & or using steering wheel controls, etc?

From the very niclely done http://********************/smile/emthup.gif DIY instructions, it looks like it will require a dealer software install to activate the controls on the head unit's audio controls. (see Appendix A in the DIY @ the bottom.)
