I am really enjoying this gauge and am continuing to learn more about how to use some of the features. I wouldn't say that the manual is the best I have ever seen but with trial and error, I am getting all the information that I could hope for.
Although there is no glare from the sun, I have found that with sunglasses on, I can't see the numbers on the gauge. I should also say that with sunglasses on, I cannot read the car's message center, either, so that probably says more about my sunglasses or my eyes than it does the gauge.
One puzzling thing for me: Sometimes, when I start the car, the gauge boots up within a couple of seconds. Other times, it might take as long as a minute or even more to come alive. Any idea why the inconsistency?
