Thanks for comments guys and ur right, alternative readout can be selected via MFD but my situation is more about 'type approval' and the ability to have the principal readout in the 'local currency' ie KMH here in Ireland.
I have been led to believe that to import a brand new car here from the UK, traditionally the dials wud need to be swapped out. However, now its a digital display i wud hope the AID can simply be reprogrammed to display the native readout, ie KMH and not MPH.
