I just use a portable GPS, but I routinely take it even on trips where I know exactly where I'm going for 1 major reason. Instead of listening to the kids say "how much longer" 100 times, I just point to the screen and show them the time to destination. They can watch for themselves. Helps them to see the minutes count down, keeps the little devils a little less annoying

Two climate control systems, one inside and the other at the tailpipe.
