I just thought I would resurrect this thread I have posted this on BMW NAV but there is lot of expertise here now in this forum

Reason I ask is another forum member has sent me one he has bought from
Ebay it won't work with his colour screen and he asked if it could have
been fried by being incorrectly unplugged so so I said I would test it for him.

First thing that caught my eye was the sticker that says -

22.08.03 14:22:59
Fahrgestell : FY82475
Laenderkennung :F1
Display BMWM01S
Update Status :IO
I don't remember seeing a sticker like that before, can someone
translate the German words for me please?

if so would a sticker on it with - Display BMWMO1S indicate it was a
business radio MK4, Just a guess but would the M = Monochrome?

I must admit I have not heard of any MK4s being fried but I suppose it
is possible

It also has the normal BMW Sticker and the part number is -
65906920182-04
HW:1.01/SW:1.2

As far as I know that part number is one used for a colour display
version of the MK4 but the other sticker puzzles me anyone help confirm
if this is suitable for the colour display

From this thread I gather we believe these can be recoded is that definitely a dealer only option or has any one worked out a home made way to do it?

Do we know what the dealer coding does?

I am thinking could Nav tweak be enhanced to produce a Bootable CD that could do this?

And if so I guess that might make a lot of people very happy as I bet there are a lot of MK4 paperweights out there

Lastly if they can not be recoded did anyone ever post pictures of inside a monochrome MK4 showing any part missing so I can double check this one?


Thanks
