It is possible to turn off the central display on the right hand side of the instrument panel on the dashboard. I can turn the left off so I can see the full rev counter needle but not the right side so I can’t see the full speedo needle. The traffic sign display and forward distance radar don’t seem to have options to toggle them on and off. Unless of course someone knows better !

Actually folks I worked it out myself. Can’t believe I hadn’t seen this before. Just turn off the traffic sign recognition and the collision assist in the driver assist menu. This leaves only the lane departure warning, which is toggled on and off from the button on the end of the indicator stalk.  So much nicer actually seeing the speedo needle in full.
