I finally got around to hardwiring my V1 in my car, a very quick process when you know what you're looking for. I'm trying to find a sufficiently stealthy install, ideally to save me the hassle of dismounting it each time I hop out for lunch, etc. I'll probably still take it down when I know I'm toast (IO or Laser), but having it hidden enough from cops would be a plus too. Anyway:
Variant one: just mounted high with suction cups. Not very stealthy, but it does the job with detection and it's quick to take off.
visor clip goes into the top, it sits straight, suction cups don't fall off every two seconds, but it faces the black dots on the top of the windshield. If this doesn't affect detection terribly, I think I'll keep it, but otherwise it's going back to the normal state.
Sadly the black dots cover all the area where the visors themselves don't prevent me from mounting it like this, and it's hard to use the visors because A) it points down B) I actually use mine.
