INTRODUCTION
The AXAC-MZ2 is a camera switching interface that provides up to (3) additional camera inputs
to the factory radio, while still retaining the factory camera. With this interface a front camera,
and/or side cameras, can be added to the factory radio. The cameras function automatically, no
human interaction required, unless desired to do so. The interface can also be used if the vehicle
doesn’t come equipped with a backup camera, adding up to (4) cameras in this scenario. Axxess
recommends cameras from the iBEAM product line for best results.

• Disable (will turn off the input)
• Backup Camera (dedicated backup camera)
• Left Blinker (will be used for activation)
• Right Blinker (will be used for activation)
• Control 1 (positive trigger activation)
• Control 1 (negative trigger activation)

video trigger 4)
Video trigger description
• Reverse camera: Dedicated by default to Video Trigger 1. Will activate the backup camera
while the vehicle is in reverse.
• Left blinker: Activation of the left turn signal will activate the left camera.
• Right blinker: Activation of the right turn signal will activate the right camera.
• Auto (reverse -> drive): Available only for Video Trigger 4, when installing a front camera. With
this feature selected, the camera will activate automatically once a reverse-then-drive sequence
is seen from the vehicle. Example of this scenario would be while parallel parking the vehicle. As
an alternative, a control wire can be used instead to manually activate the camera
.
Note: Auto (Reverse -> Drive) will disable the camera once 15 MPH is reached. A control wire
activated will also disable the camera.
Note: If the control wire is activated while driving, the camera will activate and deactivate
during stop-and-go traffic.
• Control 1-4 (positive or negative) trigger activation wires: Can be used as a positive or
negative trigger to manually activate a camera via a toggle switch, or similar device.
