Momentary maps of reason

The Jag’s all-tft instrument panel can be configured into one of four different display styles; my current favourite is ‘Torch’ which only illuminates the numbers of the tacho and speedo relevant to the sweep of the needles. But given that the numerical speedo display is the easiest to read at a glance, I’m unsure why I really need the gauge. More useful is the option to have the navigation map filling the whole screen, with speed and fuel level miniaturised.
