i was looking at my dash today and in the part that has the gear selector and the odometer i notice that next to the P it can also display a digital MPH, and below that it also looks like a Rear Sonar indicator? do they use the same instrument clusters in infinities and that is a option on them? or how about does any one know how to activate both features? or even any one noticed it at all? it was at dark out and i was just listening to the radio and looked closer at the that part of the cluster.
