Nav System Question
 

I don't have a user's manual for the 2007 GTs I just purchased at auction.

The car has the nav system that pops up out of the top of the dash. (tilt button the left) (open button on the right).

My question, I'm hoping, is a simple one. Is the stock screen supposed to be touch screen? It only seems to respond to the controls by the shift knob.

Thanks for the quick response!
