Tools and additional components
You will need:
•A Phillips-head screwdriver when mounting the unit in the vehicle
•4-6 screws to attach the ceiling bracket to the ceiling of the vehicle (not included)
•High-quality RCA input-output cables
Extra cable can cause signal loss and act as an antenna for noise. Use only high-
quality RCA cables that are no longer than necessary to make a direct connection
with the source unit(s) and monitor.
Before you begin
1. Verify that the vehicle electrical components function, including: power windows,
power door locks, air conditioning, lights, etc.
2. Test fit the location of the overhead monitor system to ensure it will not interfere with
the operation of the vehicle.
3. If applicable, verify that the monitor, when mounted, will not interfere with the
operation of the sun roof.
4. Determine the location of the audio/video source(s).
5. Disconnect the negative battery terminal before making any wiring connections.
CAUTION

Do not open the case. There are no serviceable parts inside. If

you drop anything into the unit during installation, consult with

your Clarion Dealer or an authorized Clarion service center.
