I have hard wired my i955 into my fuse box using a add a circuit, I have used the radio, sunroof and other circuits but none will turn the detector off when the key is in the off position and removed from the ignition yet the device the fuse is working turns off. i.e Radio. This is being done on a 2004 Volvo. Is there a relay of some sort and is power always at the fuse box? Not a big problems as I just need to remember to turn off the detector each time. No matter what it's a much cleaner install. Detector is mounter just to the left of the rear view just under the tint.
