Mine is above the mirror as well, complete with the extension cat5 cable with male/male connector. But I used an old GPS suction-cup mount I McGyvered to work with the ScanGage II. You can't see it behind the mirror, but I can adjust it so the top of the SCII just touches the mouse fur on the ceiling, preventing any vibration at all. And I can angle it to see it perfectly. Plus, it's instantly removable for use in other cars, or hiding from unethical valet parkers.
