SWAPMYRIGS come to you as a set of two SMR boxes, configured for your particular radio. We include the cables to connect each SWAPMYRIGS unit to your transceiver's microphone, control, and audio jacks.  This includes our 15' shielded VGA cable. The 15' is the perfect length for most car and SUV installations.  Longer cables are sold separately, based on the length required to separate your controls from your radio. Each SWAPMYRIGS box measures 2.6" x 2.6" x 0.9".
