Didn't know you could enable the speed to appear on the radio! Shame its in kph though but anther little gimmick found in VCDS. Its enabled by selecting adaption channel 2 in radio - or when the radio is off hold down menu for 2 seconds then the power button and menu together for another two seconds.
Then turn the radio on.
VCDS does say that it will not work on all radios, I have a bog standard rcd300.
