Re: AU1 Fairmont Head Unit Replacement
first question - i think its clarion that make hus that are adaptable for au falcons and there steering wheel controls, otherwise, hunt down the products made by aerpro and u will find that they stock adapters that will allow you to use aftermarket hu (depending on brand) with the steering wheels controls..
2nd question, as far as i know those steering wheels buttons are on a small circuit board that. they operate on different ohm-ages which determine what signal the hu gets so are basially usless if u try and wire them up to another hu..
as for ur 3rd question.....cant help u sorry
