Yep it's called the Intelli-Cord and their newer RDs can use it:

Intelli-Cord™

Using Whistler’s optional Intelli-Cord™ Power Cable allows some models to control the detector’s features such as Power On/Off, City Modes, Dim/Dark, and Quiet/Auto Quiet with a simple press of the button on the Power Cable.
Two features can be controlled: one by a short press of the button (S1), and the second by a long press of the button (S2). Option Mode allows the user to program the feature assignments.
