Sounds interesting, let us know how it goes. Would be interested to hook up my steering wheel controls to my carputer. That or to my HU, not sure yet.
One question you might be able to answer me. In my 53 reg glovebox, under the plate thing in the middle, I have a box stuck to it. Any idea what this is? I'm curious as to whether my Carnetix PSU is causing interferance with it as since putting my Carnetix in I seem to get more noise on the radio. Not sure if I need to rewire the power to the antenna or if its this box I'm interfering with or something else near the glovebox.
