Both those options would be a useful test.  :y Having said that, the GID only used the larger plug and it displayed all the fuel / speed info, so I assume the info is sent through the wiring to the larger plug ?
Havent studied the wiring diagram yet, but what is the smaller plug actually for ?

Its RGB Signal (Red, Green, Blue) to feed the Map infomation, the other Graphics info are part of the CID Screen.

If the NCDC controls the functions`on the CID then I guess there will also be a control pair (and possibly a speed pulse going the other way)

Just got a message from the seller saying that the unit will need to be married up to the engine and wheel / tyre size, using tech 2 to get the consumption correct.
Never heard that one before.  ???
Sent me this link to get the correct codes.

Final drive and gear ratios vary between engine and gearbox combinations, but all Omegas have the same speed signal generation, ie from the ABS, so unless it's come from a 2.2 dti, the consumption should be in the same post code :-\

I have asked him if he knows which spec car it came from. He originally said it came from his own elite, but the opel logo threw some doubt on that. Not many Opel Omega elites in Kent.
The strange thing is that the average speed shown seems to be ok, just the fuel data which doesn't work. I think a little blast of electrical cleaner and a shot from an air cleaning aerosol in the recess where the large plug sits is all I can do. After that its deciding whether or not to try and take it back out and send it back, or to just live with it.
I really like the look of it in the car, but I don't fancy having no fuel consumption figures. Decisions, decisions.  ::)
Btw, Doc. I have had a look at the wiring diagram, but cant make much sense of it tbh.  :-[

The left bit plugs into the right bit and when power is added, the pixies do their thang :D

OK, lot of guff being said.

MigV6 - what is the CI on the CID?  What spec is your car (engine, gearbox, Xenons, wheel size)

Don't know what that means. :-[
I take full responsibility for all the guff.  :-[ ;D
Car is 02 3.2 elite auto. 17 inch wheels, 235/45/17 tyres, xenons. Standard 02 elite spec I would think.  :y

To save you trawling through 5 pages - everything seems to work fine apart from average and instant consumption figures. Instant reads 9.5 (?) gallons / hour at standstill and 7.1 when moving. average reads 7.1.
Been reset several times but reverts back to this.
Only other problem is that the genuine navdisc looks good but cant be read. Copy disc (2010 iirc) works great, but obviously not good to keep using it.

Sorry, CI = Code Index.

Can't remember the exact method for finding it - it involves putting NCDC into diags mode by pressing MAIN for 6s. But can't remember which page the CI is on  :-[.

I believe you need CI of 074, but will check once I have confirmed how to check without Tech2 - can you wait a few days until I can get to a car?


Sounds like CI is wrong, easily changed, but needs Tech2 :(

Sticker on the rear of the CID has a lot of numbers and the letters KJ on it. Would that be the CI ?

No. CI is a configuration profile programmed on via Tech2 to make it right for the specification of each car.

Only way I know of finding it without Tech2 or certain other dodgy Opel specific coder readers, is via diags mode on NCDC
