E60/E61 Manual LCI gear shift indicator: Put key in, press start button twice (ignition on), press/hold BC button for 3 secs activates the 'up/down' graphic. I had to move off the mpg to the 'blank' otherwise it resets the mpg number instead. Going for a drive in a mo... probably a generic economy suggestion gear indicator.
Problem solved.
I held the BC button in for a few seconds and it appeared.
