also check for compatibility with your service provider/phone type. i believe certain phones do not give off the right type of signal to trigger the unit. same thing with the little fashy air freshener thingies that light up when you have a call. i have sprint so it doesn't work with mine. it lights up when other peoples phones are in the car though.
