Truth is though, if it is a temporary setup for the trip, the screen makes little difference, unless you plan on taking the screen out of the housing and installing it in the dash when you get to that point. Then go with the better screen if you can afford it.
As for your NAV program. I believe there are better for routing and Nav. I like the IG/Routis family, with IG2.1.1 being a great product, especially with the upgraded maps, and some other nice functions. But, Nav programs are a personal preference. It depends on what you like to use.
