This is connected to the Nav computer in Connector X1312 at pin 7 (labled in docs I've seen as 'Signal Nav Bus'..

Does anyone know the format of the signals that go down this wire? This LCD appears to be used in my MG ZT within the IKE and I'd quite like to drive it from the CarPC I'm developing.

But I need to know the format of the data on that wire and I can't seem to find any info on it anywhere.

Any help would be greatly appreciated.
