Well based on the pictures i have a high line.
Since I was/am the first owner 100% certain the car came with that unit (still is in) and also had navigation installed (the unit in the back (now broken by the way).

The "monitor"was there from new (see also the pictures linked to #0800 on the register here).

Will wait for my parts to arrive :-( Still no sign.
I am handy with electronics so will make a first attempt myself but good to know there is an expert around.
(I will not sell the spare displays. Whole point of buying two was to have a spare should i ever need one.

Fix vintage audio as a hobby and parts like these become very difficult to find at some point in time.
So would advice anyone to buy an extra and store it for the future (if anything the parts will not become cheaper).

As for the unit I bought 15 years ago. Will keep it for spare in case the speedometer or rpm meter breaks.

Thanks,
Peter
