Activating the ODO/TRIP Economy Guage

[errolfletch]

I own a 2008 YRS 3 Door hatch which has all the usual Australian manufactured parts and standard fittings and comes with the YRX universal digital dashboard...ie digital speedo in kms, digital fuel bars in litres, digital sweep bar tacho etc. The clock portion of the "Combination Meter" also has the ODO/TRIP/ECONOMY inbuilt into the electronics but according to an Australian Toyota Service agent, the trip part of the combination meter does not come activated for Australian owners. The O/T/E digital display is only visible when a strong light or sunlight is shone where the clock module is. It appears to be the same as the Canadian version ie kilometres and litres with the clock alternating by pressing the clock set switch.
Any ideas how to tell what is missing to get the O/T/E functioning and where do I purchase the relevent module and wiring harness (which ever is required). This would certainly save putting in a non genuine after market part which I would prefer. Apparently the South African Yaris has this feature as standard.
