It appears that the Avic 8000NEX in its current configuration does not support the feature of displaying car information with 'gauge like' screens. In fact Maestro told me on the phone that the Maestro RR only controls the steering wheel radio controls that are on the steering wheel.
My question to all of the AVIC experts is: do you think that Pioneer will 'correct this' in the future?
Will the correction be in the manner of a Software/Firmware (not sure of the correct term) update?
This iDataLink 'feature' is available with Kenwood and Alpine head units. It is basically reading the ODB II info from your car.
It has 5 Gauges with the option of displaying:
Boost/Vacuum
Distance to empty
Engine Load
Engine Coolant temp
Engine Oil temp
Exhaust gas temp
External air temp
Fuel pressure
Instantaneous fuel economy
Intake air temp
Intake manifold air pressure
Mass air flow
RPM
Throttle plate position
Torque
Timing advance
Transmission Fluid temp
Vehicle speed
