Thanks guys, I was not knocking the unit or trying to start trouble? The unit I have from usaSpec required no cutting or splicing It came with a harness that plugged in line with the existing stereo harness, and a Coax runs from there to the usaspec adapter. In fact I can plug this cord into the adapter or CdChanger and the head unit does not know the difference? With my Ipod I push the CD button on the Touch Nav unit and my Ipod comes on. Do any of you know if this unit can be installed in the same way? i.e. in place of the CD Changer and retain all its features that are superior to the usaSpec unit? I'm going to call the manufacturer tomorrow.
