I think that might be true, which makes the Invisicord useless. I am not turning the detector on and off every time I drive. I guess I'll have to find another way to wire it.rocastro71 wrote:The ground wire is the middle black wire. When you push the invisicord in, the white plastic pops out slightly when the wire goes in. Then you can plug it back to the rearview mirror.I don't know what year is your car but it might have the hot plug (12 volts all the time). That means you might need to manually turn your radar on and off all the time or for my 9500ix, it automatically shuts off after 4 hours if the car has a hot plug which mine does not.
