I finally figured out how to adjust what it thought OFF ROUTE was to a more generous setting and it shut up.
On a trip on Route 17 (the major road in the area) to Binghamton NY, a relatively-new (and updated) Garmin showed us flying through the air (I guess) rather than being on the road we were on! It would even snap-to roads that we were close to (using that them to reroute). Kind of amusing.
I think that either the map was stale (and didn't have the exact location of the newly-widened/moved roadway).
Or that the GPS position was not accurate enough.
It's actually amazing how well the devices work.
Knowing how they work (and their limitations) lets you roll with their quirks.
(Next time you feel you need to trow it, throw it my way,
gently!)
