I need a handlebar mounted GPS pretty badly. We ride tight woods. Every turn looks the same and after 15 minutes you don't know north from south. My friend is doing GPS duty for the group and lets just say we've lost confidence in his abilities. So... I want something mounted on the handlebars with a screen large enough to show something. That pretty much narrows it down to the Montana and the new Android based Monterra. I find these GPSs to be very expensive ($450 and $650), considering that a crash could render them junk. People complain about the Montana software. The Monterra runs Android which theoretically means I could use on of the seemingly good GPS packages available for it. My Samsung S4 is expensive too, but I already own it. It runs Android just like the Monterra. It seems to be able to do most of what the Garmins do, with the exception of having poorer GPS resolution. Is it feasible to use a cell phone as a high end dirt bike GPS ? Is the Monterra worth the premium over the Montana ? Is the Montana the logical choice here ?
