So you can keep your attention where it belongs, SAVVY turns down the volume of V1's alerts automatically at low speeds. SAVVY has just one control, a thumb wheel to set a speed threshold. Below your set point, the audio comes through on V1's Muted Volume (set this with V1's Control Lever). Above the threshold you hear the normal loudness you've set with the V1's Control Knob. SAVVY stays nearly out of sight down near your steering column where it serves as V1's power source. It replaces the Lighter Adapter or, in "hiddenwire" installations, the Direct-wire Power Adapter. Just plug SAVVY into the OBD diagnostic port, standard on every new car and light truck built since January 1, 1996. Then plug V1's power cord into one of two RJ-11 jacks (the other works with the Concealed Display or other V1 accessories). The thumbwheel has eight setting between 15 and 65 mph. Choose one, or select AUTO, which mutes all alerts, or choose NONE to eliminate automatic muting. SAVVY is ideal for those who want to hide V1's power cord. Two wire clips and a beaded tie strap are included to secure the power cord to V1. SAAVY fits in the palm of your hand and weights just 2.2 ounces. Black only. NOTE: SAVVY draws a small current from the car battery even with the ignition switched off. Use caution in vehicles with weak batteries, or that go for long periods without being driven.
