Otherwise, the Responder one lacks a number of the 1.2's features (trunk release, manual transmission mode) but still sports important core features such as Virtual Tach, a 2000 ft. operating range and Aux ports for expanding functionality.
The Responder one's two included one-button remotes offer basic and simple functionality which also makes them extremely compact for greater portability. Its Virtual Tach technology allows the Responder one to monitor your vehicle's voltage, making a physical tach wire unnecessary. Additionally, the Responder one's Aux ports allow users to add extra functionality (unlock while running, horn honk, defroster output) easily.
