I just bought the Whistler PRO-68SE. It came with a hardwire kit which is one of the reasons I bought this particular detector. I want the detector to turn on/off with the ignition of my car. I used an add a circuit and wired it in with my car stereo. The unit works fine other than not turning on and off like I want it to. I know it has the power saver mode so it stays on for six hours after I turn off the car. I guess I can live with that but what really bothers me is the detector does not come on when I start my car. I have to hit the power button to turn it on. Shouldn't it turn on automatically when I start my car because I have it wired in with the stereo? Is there something I am not doing correctly. Appreciate any info. Thanks.
