Thanks for the notes! I'm following that car with interest.
Gauge test sweep has been selectable on XTs from the beginning (MY05) not sure about other models.
Regarding the dash display- are your sunglasses polarized? Try tilting your head to see if the display brightens and darkens in response to the angle of your head. Lots of automotive LCDs are done right- polarized at a 45° to the horizon, so that polarized sunglasses don't make too much of an impact on brightness. Unfortunately I've been seeing more which aren't designed as well and become unusable with polarized glasses.
