Getting to Know Your Radio
Major Radio Components
Your radio has two major components: the radio unit installed in your
vehicle and the control head that is used to activate various radio
features. You may also have radio accessories installed based on the
specific configuration of your radio.
This user guide describes how to use your radio and its control head.
The foldout page inside the back cover of this guide contains an
illustration of the W3 control head showing all the controls and
programmable buttons situated on the control head. Keep this foldout
open as a reference as you review the procedures in this user guide.
