You do now lol, was reading TV, and came accross it in the problems section! basicaly is says to access the digital readout you need to,
for colour screen or MFD
press and hold the settings button on the radio untill it beeps (takes awhile) then scroll through using the BC button, some other random stuff on there too!
for normal TID display
same as above but use the little the little dot on the display next to the clock one!
Had a go to day and its really strange!
