I'd REALLY like to see a demo of this. I"m sitting in the lunchroom with the former head of R&D who holds a Master's in EE and has several RF-related patents on antenna design and when I described this one to him, he looked like I felt: "What the hell????"...................


Just to be clear: You refer to the "radio/NAV" - is this unit the factory one or an aftermarket replacement?
