FAQs
Q. The unit will not power on, I have no indication of proper operation.
A. This module
will not
power on properly or display anything (reverse image or AUX
video IN) until CAN is properly connected.
Q. All I see on the display is a black screen (no factory image pass-through).
A. Verify the video cables (IN/OUT) are connected at the proper location (
at the radio
).
B. Verify you’re using the correct LVDS video connector (pink or gray).
C. Verify Dip Switches are set correctly.
Q. Nothing happens on the media screen when I place the vehicle in reverse.
A. Make sure DIP Switch 4 is the DOWN position (pull power from the interface first!). If
still nothing, try placing DIP Switch 5 in the opposite position (pull power from the interface
first!). Also, DIP Switch 8 must be DOWN, always.
B. Try a different year setting (with same model) from the Dip Switch chart.
C. Verify 12v (+) and ground to the interface.
Q. Rear camera image does NOT appear.
A. Verify Dip Switch #4 in set
down
for aftermarket camera, or
up
for a factory camera.
B. Verify the CAN wires and location of CAN connection.

at the camera itself.
D. Try an alternative video source, don’t assume the power/ground is correct unless
you’ve checked it
with a multi-meter!

green wire instead of the CAN connection for reverse activation.

OEM->RGB->AV1->AV2->OEM).
