I think that the Garmin would more directly compete with the Proline Fusion package. Rather than the Proline 21. It is set to be delivered on the G250.
As far as the touch screen on the G3000. If my information is correct Garmin has considered turbulence and added a turbulence mode I believe. Something with larger simplified touch icon, or something to that affect. I have a brochure around here somewhere.....I need to get it out and look at it.
