Installation guide

CONNECTING THE DOME LIGHTS
The dome lights on DVDM-800 require three
connections to the vehicle wiring. First, determine
which of the two common types of dome light
circuits your vehicle has: positive or negative
switched. Positive switched systems turn the
interior lights on by supplying voltage to them.
Negative switched systems illuminate the bulbs
by applying ground. The wires at the dome light
will help you determine which system you have.
• On a positive switched system, with all vehicle
doors closed and lights out, both wires at the
dome light will rest at ground. When the light is
turned on, one of these wires will switch to
+12V DC (the vehicle’s switching wire).
Connect the purple/brown (lamp auto) wire to
the vehicle’s switched wire. Then, connect the
red/black (lamp on) wire to a fused constant
12V source and the black/red (lamp common)
wire to a good ground.
• On a negative switched system, with all vehicle
doors closed and lights out, both wires at the
dome light will rest at +12V DC. When the light
is turned on, one of these wires will switch to
ground (the vehicle’s switching wire).
Connect the purple/brown (lamp auto) wire to
the vehicle’s switched wire. Then, connect the
red/black (lamp on) wire to a good ground and
the black/red (lamp common) wire to a fused
constant 12V source.
Note: Some vehicles incorporate transistorized control of the
dome light circuit and may not support the additional current
draw of the video monitor lights. In these cases, it may be
necessary to connect the purple/brown (lamp auto) wire to
the door pin switch wire.
SYSTEM TEST
When installation is complete, test the following:
1. Power connection
2. Dome light function
3. IR remote control
4. IR headphone function
5. A/V input/output functions
6. Wireless FM transmitter functions
TROUBLESHOOTING
If the Delphi Mobile Video unit does not appear
to be functioning properly, please follow these
troubleshooting guidelines:
No power at the DVD system:
1. Verify 12V DC power at the power cable
behind the video monitor.
2. Verify the ground connection by conducting a
continuity test from a known good ground to
the black wire of the power cable.
Power on, no video or sound:
1. Verify selection of the correct A/V source
(A/V1, AUX, or built-in DVD): Source should
be “on” and playing a known good DVD.
2. Verify connections at both ends of the source
component harness.
Picture with no sound:
1. Push and hold the volume up button on the
remote control until sound is heard over
wireless headphones.
2. Make sure radio is tuned to the correct
frequency for the FM transmitter.
3. Verify all connections per the electrical
wiring diagram on page 6.
Remote control doesn’t work:
1. Check the strength of the two AAA batteries;
if they are weak, replace both batteries with
new ones.
Refer to the Delphi Mobile Video DVDM-800 User
Manual for additional troubleshooting information.

Warning: Failure to properly follow these instructions
could result in damage to the vehicle, its electronic system,
other property, or personal injury and/or death.
