Was delighted to find how easy it was to upload gpx. files to my Garmin Instinct. I need gps for biking the back roads of of rural Virginia. Started merrily down the road, it indicated my first turn. Wow, this is working! But I found as I rode along I would get an 'off course' alert if I so much as deviated from the shoulder of the road to the middle of the lane. There seems to be a 1 foot wide sweet spot that you must stay in or you get the 'off course' message and the thing becomes annoying as it tries to find and get me back on course. Is there any way to set it so the the 'on course' tolerance is wider?
