I have a 2006 build mk4 which works in my 2001 540i fine but if I try to talk to it with NCS (INPA) it errors saying incorrect address!

Am i right in thinking BMW changed the address of the nav unit in 09/05 build nav units?

Does anyone know how I can edit my ZCS to include mk4 nav (presently MK3)
& add DSP & ULF with SES to the ZCS?

Regards

Jason
