The display at the top of the touchscreen is easiest to use since it is more in line of sight while driving. However, the lower display would let me turn off or calm display the touchscreen much of the time. The main dash display already includes navigation directions, song titles, compass, outside temperature, phone numbers, and more. Yes there is a lot of other stuff on the touchscreen, just not things that I need all the time. Not saying I would for sure turn off the touchscreen, just saying it would provide a more complete option. I like having mechanical controls and I am guessing this may be the last year for those on the Explorer. Next year may bring Sync 4 or 4A. Those, especially 4A, tend to place all controls on the touchscreen.
