It's rare enough you have the factory nav system, let alone getting a wiring diagram for it. If someone does translate it for you, let me know. I would like a copy of it.

If you don't find anyone, I can ask a friend that reads Japanese, but I won't see him for a few weeks.

Fantastic find mate, I also have a friend who speaks Japanese, I'll see what I can do. Quite interested in this as I have the sat-nav system as well. Obviously the system itself is useless, but if I can figure out from the wiring diagram how to raise/lower the screen and get a picture to it then the possibilities are endless...

Et Voilà!

Page 1 is described in prose thus:

Seems to be a schematic of the "Multi AV system".

Page one points out where things are around the car. The labels
clockwise from top left say,

Display Unit
GPS Antenna
Voice Guide Speaker [I assume for the satnav?]
Front door tweeter [lit. "tsui-ta-", took me a while]
Front speaker
Rear speaker
TV Antenna Amp Right
Vicon unit (Dealer option) [Do you have the mysterious vicon, or maybe
bicon, unit?]
TV tuner
TV Antenna Amp Left
Radio antenna amp
Electronic tuner radio
front speaker
front door tweeter
NAVI C/U

Then the next page is the "block diagram"

Down the left column it says:

GPS antenna
Speed meter (vehicle speed signal 2 pulse)
reverse lamp SW (M/T)
Inhibitor SW (A/T)

[I guess M/T and A/T are manual transmission and auto transmission]

Parking brake SW
Stop lamp SW
Earth (M/T)
Inhibitor SW (A/T)
Light SW
TV glass antenna
TV antenna amp

Middle column says, top to bottom:

NAVI C/U
(FM multiple tuner included)
TV Tuner

Next column:

radio antenna amp
radio glass antenna
display unit

Then the bit in the dashed box is the dealer option vicon unit again.

Next column is:

MD integrated AM/FM tuner radio [I thought we already had one of those
in the NAVI C/U? Maybe the Navi one is for traffic news].

Finally:

Speaker front
Speaker rear
Page 2:

OK now I've calmed down, a few observations from the land of total electronics armaturehood.

Who knew the S15 had a TV tuner? Although the frequency ranges just about overlap, alas Japan broadcasts using an encoding called NTSC-J, not PAL, and probably a different number of lines.

There's no obvious signal to the display unit to raise/lower the screen, unless they're the unreadable ones. Mine comes up pretty much it feels like it, so I assume it isn't simply in response to getting voltage on ACC.

The presence of two sync signals (I guess ?? sync might be vertical sync) makes it look to me like the screen takes an analogue video signal (I am not an electronics engineer). The RBGHV system does this. Systems like this are used in VGA and SCART (component video like from a DVD player is YPbPr with no separate sync).

"Video picture signal" is a bit confusing.

Does anyone know what a "Vicon" unit is? It seems to sit in or close to the boot lid and have a large connection to the TV tuner.

There's a separate mono speaker for the satnav voice commands (at least), to the bottom left of the steering column. Always wondered what that grille was.
