The PP207024 USB jumper cable is the main data connection cable used for communication between the stereo (head unit) and touchscreen in the Paccar SmartNav 2.0 and NavPlus HD systems.
The ends of this cable are referred to as USB-MINI, but it's the USB housing and cable shielding that make the PP207024 different from any other USB mini cable.
This cable is included in the SmartNav and NavPlus retrofit kits. Plug one end into the black data port on the back of the screen and plug the other end into the black data port on the back of the stereo. Both ends are identical.
