I just got my 8500 X50 Blue. Finally saved the cash. I was curious where everyone HERE recommends mounting it, on dash, windshield (how high-Low). I'm in Texas so it can be in plain sight. I see alot of people who put it directly on the Dash, up against the windshield somewhat below the wiperblade. There doesn't seem to enough room, seems aweful close to wiper. My Ford Escape barely has enough gap between the wiperblade and the black strip on the bottom of the wind shield. Does being that close to the wiperblade hurt range and or performance??
