Not to hijack this thread, but I've noticed a definate trend: whenever someone includes "radar detector" in a thread title, it acts almost like a lightning rod for anyone employed in a law enforcement capacity, attracting them to the thread. And they usually post that they don't like them. Interesting. :L
I've always felt that owning a radar detector becomes, eventually, relying on the radar detector, and that leads to a false sense of security. No, I don't own one, and no, I'm not in law enforcement. As such, Guana, I'm afraid I don't have a recommendation for you on how to hardwire your V1.
My only advice would be that if you hardwire it, remember that if you get pulled over, having a radar detector on your dash will almost certainly influence the officer who pulled you over to NOT let you off with a warning.
