with that being said it will be a good idea if it comes with a brightness control, that will take care of the sun issues.I wonder how readable it is in direct sunlight. Guess I'm officially "old school" in my instrument tastes. I like analog ways of conveying info. Perhaps it could be set up to use one's cell phone/phablet as your display/cluster and key.
Not all situations can they make it still easily visible but in most cases it should be good.Assuming it has sufficient lumens and even then i think there will be conditions it may not be able to overcome. Nokia is supposed to be good at daylight visibility with their phones/tablets. Perhaps a display by nokia would be workable.
