I have the Sport EX touch screen and I've basically never used it outside of checking to see if it works. I'm day vfr only - perhaps there is something that you might need it for that I never use, so probably best to let the GRT guys convince you. The knobs and buttons work great, are well-designed, and have good tactile feedback.Does anyone have the Sport EX who opted for the touch screen? I have an EX on order and am considering adding the touch screen. Is it worthwhile?
