I've found myself in a lot of situations where the GX's navigation shows a trail that in actuality is just a goat path. It also showed me the Pacific Crest Trail as a drivable route north of Tehachapi pass. I'm honestly glad that it errs on that side, rather than being under-marked, but it's always good to have your own maps or GPS when out exploring.At least where we live (west coast), the factory 2013 maps in our GX show an amazing amount of trails with names and numbers, even more than Google Maps without having to pre-download maps before we're out of cell service. One reason why we keep the GX map displaying breadcrumbs when on these trails.
Is the east like that also with your GX maps?
Here's another prime example. Most of the trails on that GPS screen don't exist, and the one that actually does exist has a locked gate. I was glad I still had a half tank of gas when I got to this point.
