LOL - It's really not that bad. With Gaia on a decent sized screen, it auto-scrolls. Once you have the screen zoomed to an appropriate level of detail, there's no need to touch it at all. I give it a glance while on a trail, but my main use for a big screen GPS is to see trail junctions for turns, or to see if I've managed to deviate from the trail. I found that useful when wandering around Death Valley, since the trail I was on was overgrown, and it was difficult to determine when I was supposed to be in a dry wash, and when I needed to get out of the creek bed.LOL. I guess I've been lucky that I haven't found I couldn't stop and look at a map while under way. Or could be that I just don't trust myself not to cross lanes or go off the road bed so I much prefer to stop rather than fumble around with a device or map. I really am a pretty sub par driver, so I try to concentrate. It's also why I'm such a curmudgeon about not driving an automatic transmission. I find being engaged and not letting my mind wander is better for everyone.
If I want to examine a route more thoroughly, I still stop and check the screen. If I want a better view, out come the maps and guide books. Until we have cool screens on par with the ones from Red Planet, I don't think we'll be replacing printed maps.
Maybe that'll be the Garmin Overlander MkII.
