When I hit the highways in my 2011 Mustang, I have an option to turn off my Sync display and I can actually turn the instrument panel down to dark. Long stretches of West Texas highways are more enjoyable to me that way at night.
So far, it appears I don't have many options to "darken" my ride in the 2015 Ford Explorer XLT.
And, no, not going to throw a heavy towel over the cluster and the sync (:
Anybody have any other suggestions?
