DVDNavi Mod for 2005 Honda Odyssey

DVD-Navi Mod for 2005 Honda Odyssey These
instructions allow you to modify your 2005 Honda
Odyssey Navi and DVD to view DVDs on the Nav
display. The theory behind this mod comes from
Ryu's thread Video on navi with reverse camera
kit. I used a relay to choose whether the
rearview camera or the DVD signal (both are
composite video) is sent to the Nav unit, which
converts the signal to RGB and sends it to the
Nav Display. I used a switch to energize the
relay and to trick the Nav unit into thinking the
van's in reverse to display the backup camera
input.You'll need to access connectors for two
components the DVD player in the lower dash and
the Nav unit under the driver's seat.If you
have access to the Helm shop manual, the
following pages are helpfulNav unit connectors

23-162, 20-129I built a small circuit board in
a project box from Radio Shack. See my webpage
for the circuit and supplies. Please note, I am
not an EE--my circuit might not be pretty, but it
works! You should end up with a black box with 9
wires hanging out. It helps to label the wires so
you know where they connect 1. DVD
signal--from player 2. DVD ground--from
player 3. Camera signal--input to Nav 4.
Camera ground--input to Nav 5. Camera

ACC (this wire is not on the black boxit goes
from the DVD player harness to the dash
switch)I mounted the rocker switch in a blank
switch cover near the VSA button. Drill a ¾
hole for the switch. (I used a rotary tool to
remove most of the blanks support structure
before drilling the hole.) The switch fit
tightly enough that I didnt need to use the nut
to secure it. Remove the drivers door sill trim
and kick panel by pulling to release the snaps.
Unsnap and remove the following trim on the lower
part of the drivers seat the left front riser
cover, the rear riser cover, and the outer riser
cover.With your black box near the drivers
seat, run wires 1 2 under the carpet, to the
door sill, up the kick panel area, under the dash
and over to the center dash near the DVD player.
Run wire 8 under the carpet, to the door sill,
and to the kick panel area. Using a crimp-on
ring lug, attach the wire to a bolt holding the
fuel door handle. Run wire 7 under the carpet,
to the door sill, up the kick panel area, and to
the rocker switch on the dash.To remove the DVD
player, first remove the lower dash cover as
follows on the drivers heater lower cover,
carefully pry out the round trim clip, and pull
the cover toward the drivers side to release
another snap-on clip near the bottom. Then pull
the cover rearward with a wiggling motion to
remove it from a slide-on stud. Repeat on the
passengers side. Pull open the cupholder drawer
and remove 2 phillips screws below the drawer.
Remove another phillips screw on each side of the
lower dash cover. Now pull the cover rearward to
release 4 snap-on clips and move the cover out of
the way. (You may need to remove the connectors
for the seat heaters and sockets.) Remove four
10mm bolts securing the DVD player. Remove the
22-pin connector from the back of the player.
Tap wires 1 2 into the BLU and PNK wires on the
connector. Tap wire 10 into the YEL/RED wire on
the same connector and run the wire under the
dash to the rocker switch on the dash. Secure
all wires with wire ties.To remove the Nav
unit, move the drivers seat all the way up and
back. Remove two 10mm nuts to remove the kick
protector rod in front of the Nav unit. Remove
four more 10mm nuts securing the Nav unit to its
bracket and slide it forward. Disconnect the
five connectors from the back of the Nav unit.
Locate the 7-pin connector and cut the BLK and
YEL wires leaving at least an inch of wire
accessible--you will need to remove tape from the
wire loom to have enough wire to work with. Tap
wires 3 4 into the wires leading to the Nav
unit connector. Tap wires 5 6 into the wires
leading back into the wire loom. Locate the
8-pin connector and cut the GRN wire--again,
remove tape as needed to get enough wire to work
with. Tap wire 9 into the wire leading to the
connector. Noting the correct polarity, connect
the diode to the other end of the cut GRN wire
and tap it into wire 9.Your connections are
completeeasy, huh? Test it before putting
everything back together replug the DVD and Nav
unit connectors. Make sure your rocker switch is
off. Turn the ignition key to run. After the
nav system initializes, shift into reverse to
make sure the backup camera still works. Shift
back to park, and turn the key to ACC. Start a
DVD and make sure its displaying on the
flip-down display. Now, flip your new rocker
switch. You should see the DVD on the Nav
display. If your mod doesnt work as described,
re-check all your connections. Note, when the
DVD is playing on the Nav, you wont see the back
camera until you turn the rocker switch off. Now
put everything back together and go impress your
family and friends with your technical wizadry,
all for below 40 and less than a days effort.
