I would like to see polyline on GPS. First, I try to convert polyline to GPX. I uploaded GPX on GPS. SO far, I could not see the line on GPS.

First of all,is it possible to see polyline as route or track data on GPS?

What GPS unit are you using, what data source are you using for the polyline? Was it a GPS output? – lewis Feb 10 at 16:00
I'm Using Garmin GPS map62S. Data source of polyline is polygon(I converted on QGIS). – Jermain Marthin Feb 11 at 21:58
It is possible, I'd check the data format and the help instructions that come with your unit for the relevant steps and see which step is the problem or which format other than gpx might be suitable, you could just reupload the output without a conversion I would think, does you unit support this operation is the only other thing I can think of, most modern gps units with a map display should. – lewis Feb 12 at 13:02
