Thank you very much indeed --looks like it would do my job fine --can you give me the product name and model --Ill more than likelyCan't help on a built-in unit but I've used a HUD for speed for some time now on previous cars and use it on the PHEV now. The problem was the ghost reflection off the glass unless you put an appropriate film where the display shows but it does work. The one I use now is similar to this one

which has the advantage of having its own reflector screen and being GPS it isn't hooked into the OBD or dash wiring. Downside is that its possible to accelerate and see some lag occasionally in the speed counting up if there was a signal loss (stopped under a bridge, coming out of a tunnel etc).
