We are in the process of adding a Automute external output from our Navalert GPS
(see http://www.navalert.com to understand what it is)
What you do is drive to the microwave door opener location and or drone / false radar signal
then you save your location by using navalert sid ebutton
next time you in a radius of 100 meter/yards from that location the navalert sends out signal and displays mute on its screen
this signal is wiresd to either a relay that kills detectors power or the mute button on the radar detector (easily interfaced with external mut buttons on valantine and escort/ bel detectors)
Please give feedback on this .
We call this feature "ALM" auto location muting.
