I have considered one for road trips in the middle of no where but it does justify the cost for the few road trips I take. Plus, I don't drive at night to often. I guess it all depends on the habits of cops in your area.
Thanks for the pro's and cons.
Also, to answer your original question, I have seen people mount the radar detector screen in the center console batwing (the lowest trim piece). You might be able to find a picture if you look on renntech.
