after not being overwelmed with assistance , i luckily found bmwnavi and man was that fast
i have difficulty with some IT stuff so the reason for the help thread
they talked me throu it and i downloaded the software and imgburn with the specific files in an easy to understand way
popped it in and bosh she fired up in a heart beat..so sending some props to bmwnavi THANKS YOU.

Good to know that bmwnavi supported you well, if I'd seen the thread I'd have told you what you needed to know.

cheers richard i know your a good lad and super helpfull
tbh with all this nav stuff ive clobbered together and thread hunts never even come across needing a key cd on the mk3.
well its all here now laying in the boot ready to refit..a big job im sure but this stuff i can handle
i think i might at the end fitting time need to double check i have the small connections fitted to the correct parts
not the big plugs they are self explanitory more the tiny push on black wires they came loose in a bag.

There is only one condition under which you need the key CD, on a Mk III going from full screen (lower than 3-1/40) to split screen (3-1/40 or higher) software. If you ever downgrade from Split to Full screen and then upgrade again, the key CD is not needed again.

Which tiny push on black wires are you referring to?

 

[dan.]

some come off the loom to the trimble, radio and nav computer all have 1 or 2 push on plugs silver ends
and gps antenna ,getting them linked wrong will cause probs

Yikes!

The Trimble you can disconnect anyway, you don't need it.

You have all the pinouts for the various modules don't you? So 'just' a case of determining which is which by either following the coloured cable back or process of elimination.
