My wife gave me a Garmin ETrex Legend GPS for Christmas. The main purpose for having this will be for off-road use. I would like to mount this to the handlebars on my WR and I would like to know what will work best. I suspect that vibration will be a big issue. Is there a good, vibration-isolated handlebar mount that people have used and would recommend? Would it be better to just get some sort of holder that could strap to the front of my chest protector for easy-access? Thanks!
