I got my wire from mirrortap.com. it took me all of 15 minutes to install. I used my last car's mount for the radar detector. Take a look at their site, as there may be enough pics and instructions to help you out. If not, reply, and I'll take a pic when I am back.
I would love to to a concealed display integrated into the rear view mirror with my V1 I am trying to find a company that will do it. I know they do this for BMW Porsche Mercedes etc. Integrate it right into the rear view interior mirror itself. Still looking for someone who does it.
