The system supports a front camera and turn signal cameras in addition to the reverse camera. Each connects to its own AV input, and the turn signal cameras trigger from the indicator circuits.
Turn signal cameras are worth wiring properly on wide vehicles and on anything with poor over the shoulder visibility. On a Patrol or a G-Class they are used on every lane change.
Front camera and signal light camera input pins and trigger wire identification.
Camera settings are found under the System Settings, where each camera can be set to FLIP or UNFLIP and FLIP Mirror or UNFLIP Mirror.
