Thought I'd post this as a new subject since the recent availability of the Pioneer part necessary to make this happen just resurfaced (see the buy/sell forum)
Ok, here's the link to the VOMN instructions at acura-tl forum:

Here's Steve's instructions in a nutshell from the May 2001 time-frame (eons in Internet-time
). That URL above takes an OBSCENE amt of time to load on my browser, so I thought in the interest of saving time & consolidating info, I'd repost the step-by-step here.
Steve, please let me know if anything has changed since you posted this; I'm still confused by the GEX stuff, but was curious if the AVC-RGB1 is the way to go still? TIA

video decoder instructions:
materials required:
(1) Pioneer AVC-RGB1 video decoder - Available from sources on the Internet or from Pioneer Electronics dealer for $100 -
$150.
(1) 4PDT switch - A electronics store "Active Electronics" stocks these, Radio Shack does NOT. Or the switch I use can be
ordered on the internet as part #8405
(3) 18" of 4-conductor shielded wire that can reach between the navi display unit and location of your 4PDT switch. I like to
use wire with a green, white, red and black conductor(s). The color wires will match up to the Honda wire colors (except for
the black that is used for the yellow wire).
(1) package 16 pcs. of Radio Shack small telephone butt-splice connectors.
misc. Solder and shrink tube
Instructions:
Solder each of the 4 conductors from each wire to your 4PDT switch. This is a total of 12 wires to be soldered. Match all wire
colors to the 3 switch posts. A large shrink wrap tube around the switch and posts makes it safe and professional install.
Also wrap all the wire shields together (NOT connected to the switch).
Once you purchase the Pioneer AVC-RGB1 you will need to make the following modifications:
1. Open the decoder up by removing the 5 screws.
2. Pull up the power wires and disconnect the plug from the circuit board.
3. Remove the printed circuit board by bending the two metal tabs straight and removing a screw.
4. Once the circuit board is out you need to locate the DSEN test pad on the back of the board. Use a small piece of wire
and jumper the DSEN pad to a GND location on the back of the board or bring out this wire to mount to parking brake
switch. Note: The DSEN signal is "Display Enable" and it tells the AVC-RGB1 circuit that there is a display connected. It must
be shorted to ground to enable video.
5. With the circuit board removed located the hole next to the rectangular opening where the green connector goes. Bend
the tab out of this opening and feed one of 4 conduct wire through the opening.
6. With the board still out locate the 4 bare exposed wire jumpers on top of the circuit board next to the green connector.
With the connector facing you these jumpers left to right are Red signal, Green signal, Blue signal and composite sync. Use
the wire you put into the box and Solder from right to left (because it's easier) the green, black, red and white wire to these
jumpers (rememer these colors are from right to left!). Take the shield from the wire and solder it to the diode solder joint
(GND) on top of the green connector.
7. Put the circuit board back in the box and plug the power cable back in.
8. Now intercept the video signal to the navi display unit with the 4PDT switch. The wires from the center poles on 4PDT
switch need to be connected to the display units input. The other sets of 4 wires each go to the wire harness from the navi
computer and the decoder box. Matching wire colors to the navi plugs wires.
9. Connect the decoder power wires for up to the navi display unit OR car stereo power leads. If hooking up to the navi
display unit 20 pin connector make the following power connections.
Orange = Pin 1 (constant power)
Blue = Pin 2 (accessory power)
Black = Pin 10 (ground)
Yellow = No connection (Illumination)
10. Cut 1 to 2 inches back from 20 pin connector on the navi display the white, red, green and yellow wires. The white wire is
the (R) signal on pin 8, red wire (G) signal on pin 9 and yellow wire the (B) signal on pin 18. The green wire is the
(Sync)signal on pin 19.
11. Using butt splices match each of the 4 wires to the 20 pin navi plug (white, red, black for yellow and green). Crimp
these connections. Do the same for the 4 wires in the wire harness. The signal flow and connections will route like this:
Navi computer -> Wire Harness -> 4PDT switch
Display <- 20 pin connector <- 4PDT switch (center contacts on switch)
Pioneer AVC-RGB1 decoder -> 4PDT switch
12. Plug in your composite video source and test, put the dash back together and enjoy the show!
This is about all the instructions needed. Hope this helps a few of you. And of course no warranty is implied or intended with
these instructions. Your pretty much on your own if you mess it up.
Best of luck,
Steve
