TB, have seen on German auction site a CANBUS simulator for putting a CANBUS Audi radio into an older NON-CANBUS car, and this £25 little box of tricks gives the ignition sense signal to turn it on and off. I`m going to have a play to see if it can be modified in any way for use on the Omega, but mention it in case you get to research it before I do.
 

I'm sure I've seen devices that will take other signals - vehicle speed, RPM, etc. and send the information on a CAN bus. Can't remember where I saw it or why I was looking though.

It probably wouldn't be that hard to build something. Plenty of little microcontrollers have built-in CAN interfaces these days and the head unit would probably only be a "consumer" of CAN packets, so you probably wouldn't have to talk to it interactively, just simulate a subset of the packets that would be spat out by the rest of the car.

Hmm. another project to add to the pile.

There are many interfaces out there advertising speed pulse, ignition, reverse etc etc, but 99.9% of then are for putting a NON-CAN stereo into a CAN car, exceptionally rare to see it the other way around - but if you do ever see anything that is Non-VAG, please point me at it

Ahh.. It was this I was thinking of, and it does it the wrong way round.

Yep, thats the wrong way round -

Someone on another forum has pointed me at this though

According to the description that gizmo just simulates a 'switched live' when it 'guesses' that the engine is running based on how the permanent live voltage floats (I'm guessing it's really just looking for a voltage >12V).. is that what you're looking for in a CANbus headunit? I thought it was the other way around.. (you needed the CANbus 'on' signalling rather than just 12v presenting on a wire)

 :-?

Seems to generate a switched 12v supply from a permanent 12v supply by sensing the noise level on the permanent 12v supply to detect ignition switching, so no CAN conenction. Smacks of a bit of a bodge to me. :-/

Oops, my bad - pointed you at the wrong thing there -

This is the one that caught my eye

[Kevin Wood]

Ahh, OK.

Looks like it takes the ISO signals plus one additional wire. Hmm. I suppose most if it is on the ISO plug. Permanent and switched power, illumination power, speed signal. Perhaps with the addition of a reversing light feed?

Strikes me that most of the signals will be the same for any pre-CAN car, except the calibration of the speedo signal, I suppose.

The question is whether the CAN output is standardised or bespoke to VW, I suppose.

It is tempting to get a CAN sniffer and have a poke around.

This one seems to be bespoke to VW-CAN1, and does not appear to support the later 2nd generation of VWCAN2 head units

Sadly my/your recommendation for marine ply bathroom upgrade had it's legs removed in no uncertain terms. 

Mrs. KW was sceptical at first, but it's really grown on her.

So what has been done with marine ply?

I have acid (or even a cid) you could play with, but i'll need it back, and needs depairing first. But it's pointless surely!

I suppose I could take the box of tiles up there. Then it'd technically be under the tiles.
