I think the thread got a little off topic....but I'll chime in on the radar detector....

I've got a V1 stealth installed in my BMW M3, mounted in the rear 3rd brake light housing. I have connected to it a remote audio adaptor in the center console to turn it on or off, and to adjust volume. I have Jim Powell's display (see http://www.apexcone.com/Radar/RadarLove.html) and it works magically. I live in VA so they are illegal and have been pulled over twice (for other things) and the cops don't even notice.

Attenuation of signal is minimal (of course it's not going to be as good as in the front windshield), and the rear deck is cardboard and 3rd brake light housing is plastic so they are almost completely transparent to radar.

Jim will install the 'concealed display' in any mirror, so long as it's thick enough to hold the components.

Good luck!
