dope... looks like i got beat to it

theat 400r rep is stunning thanks for the link guys

Right folks, might have most of the answer to this one at long last!!. Was looking on FAST at R33 bits and came across this:---


Looks like what were talking about. I see that there is some kind of 'screen' (KF2043) which attaches to the dash which the original posted does not seem to have. It looks like it would be a fundamental part of the unit which stops the image being produced on the windscreen. Incidentally FAST describes it as a 'visual unit'. The part highlighted in blue seems to be a focussing mechanism. Its unclear whether the wire which winds its way down to the dash is an AV connector (to which you'd connect your DVD player etc).
As an aside the R33 accesories listed on FASt are quite interesting ranging from a multitude of fog light options, front and rear parking sensors(!), electric front splitter, illuminated rear 'Skyline' panel and some underbonnet neon thing.

Anyway, this almost solves the riddle. Seems its a genuine nissan part after all. Just the part about what it actually generates on the little screen to figure out now.

well, with that in hand id be straight down to nissan and ordering me the bits that i was missing, if i had that, i would now be wanting to see it work!

[Eikichi]

The thing which bugs me is that there's only a red & green light, no blue light, you'd need a blue light source to be able to project an image like on the old fixed projectors on plane
There doesn't seem to be any blue color filter either so only red & green projected
Also without a lense and it looks like it's a very low/weak light (not high ANSI lumens) I don't see how it can be used as a projector

Wow, way to use FAST, TT!

[tarmac terror]

Its what it plugs into that baffles me. I'll have another look tonight/tomorrow and see if I cant get to the bottom of this once and for all.

Clearly it is being used as such as Nissan infer this in their description of parts. My guess is that it may be a glorified speed (or other parameter) display.

Aye, maybe

Sent the link to a mate of mine who's working for Sony Ericsson & is a techy-wise about anything & he got no clue either
Could be HUD, air purifier, system to trigger traffic lights (doesn't work coz' it's on the inside) or alcohol detector (doesn't work either coz' complicated elements are missing), etc...

Doesn't the GTROC have any contact with Nissan Japan? This is really bugging me now & I want to know too

The bits shown at the start of this mean it is in no way a projector of anything but that 'cylinder' thing (IMHO etc.); there's no LCD or similar for the information to be shown on/projected from.

The FAST picture shows a 'screen' but there's no wires going to it.

I reckon the cable shown is just a power feed, but that's just a guess.

We (well, TT) have found references to what it is, but we're (I'm) still in the dark as to what it does.

Having said that, we're further forward now!

[mava_rules]

think we should all chip in a bit to get all the parts and find out what it does!
it could be our little christmas pressent lol. an answer to the riddle!

[Jim27]

I agree - that cable appears to be nothing more than a power feed. You can see at the bottom of the FAST diagram that it's Scotchlocked onto another cable - presumably a pre-existing power cable.

FAST clearly shows any cables or connections for components being looked at. There's no cable, connectors or power source for the 'display' thing that goes on the dashboard.

However if you look at it, it looks clearly designed to fold down, away from the driver.

This is my guess (and I'm pretty confident). It's some sort of parking permit/license/ticket display. The 'display' thing is raised to the verticle position by the driver, his license/parking permit/ticket is attached to it and it is then laid back down flat, so that the ticket can be clearly seen through the windscreen. If you were parking somewhere dark, or at night, the lighting system softly illuminates your ticket/pass/permit.

I know bugger all about electrics but can someone confirm whether or not the 'halogen' spot lamp thing that is used to provide the light could be an energy-efficient solution to providing light throughout the night that wouldn't drain your battery?

One of the questions that occurred to me was why would you need some daft techy fold-down paddle to hold your permit/ticket when you could quite easily just plonk it on the dash like we all do with pay-and-display tickets? Well a couple of things I thought of were a) their permit/pass could be substantially bigger than a simple pay-and-display ticket, meaning it would be much more likely to slide off the sloped dashboard; and b) if you were parking up at night then it'd be easy enough to see exactly where the light was being projected, thus putting your ticket/pass in exactly the right spot. But if you park up during daylight and intend to leave it there into nighttime, from what I've read you wouldn't be able to make out the soft projected light in daylight so you'd be guessing where exactly to position your permit/pass. Hence the fixed dashboard-mounted ticket holding fold-down paddle thingy means you get it in the right place every time.

There ya go. My brain is drained - time for tea

I'm no expert either but I think LED would be more energy efficient than halogen, no?

Jim, can I have some coffee & shortbreads please?


This whole thing is doing my head in

[tarmac terror]

Well Jim, I like your idea but to my mind;-

a) the 'screen' appears quite thick and chunky. I would be surprised if it would allow any light through to illuminate any thing on the other side.
b) Dont think Nissan would have gone to the trouble to design a fancy ticket holder . More to the point I bet it costs a bit so why would anyone in their right mind spec it on their new car???

Part KF2044 was described as a focussing unit IIRC (at work at the moment so no access to FAST) but focussing WHAT I have still to learn. If I get home early enough I will post up all the descriptions of the parts as they are on FAST.
I concur that the wire is a power feed. On that we can all agree i'm sure
Still, were a step in the right direction. Surely someone who reads these pages and works for Nissan Japan MUST know what this is for.

I'd be interested to know if it was an option on UK spec R33GTR's, obviously it was on JDM models. If so, it would be a BIG help as I'm sure Middlehursts then must know what its for.
