Got a Whistler for like over 6 years now and hardly plug it in (this sh@it is really useless, unless the cop's radar is in continuous mode. If the cop pulses you, seeing that u r speeding, then you will get a warning signal exactly a faction of a second after your speed was recorded). ... and yes, I have it mounted on the center of the dash. Looks stupid, but as I said I don't really care... If I ever decide on doing something about it, I would save for the in-dash one.
