Our Z will not turn on any of the gauges with the exception of the multitasking gauge housing the fuel, etc. only to alert you that you need a key. How is it that in the eBay ad in two (2) pictures not only are all the gauges on (indicating the mileage) and the navigation system is fully activated? The ignition switch is also lighted in the "ON" position.
