Hi all.

I recently bought a Garmin Etrex 20. I have installed a routable Brazil OSM map. Now I have also planned a 200km track, because the device has a limitation of 50 points on route mode. So, route is not a good option because of this Garmin limit.

I'm satisfied about routing navigation features, when the GPS display turn-by-turn messages warning about driving directions in my bike ride. My question: is anything featured for tracks? Something like the Garmin EDGE's do, showing directions (to right, to left is good start) during my ride?

Thanks for advance.

Where did you download the "routable Brazil OSM" from? Whether it supports routing on OSM tracks would very much depend on how the data was created.

As a bit of background, when I create maps for my own use for Garmins I create one that does route on publically accessible tracks from OSM (but not private ones) for an eTrex handheld and one that doesn't for the Nuvi car satnav.

EDIT: Aha - you're talking about following a GPS trace that you uploaded to the device I think?

I'm surprised at the limit of 50 points per route - my old eTrex Vista HCx supports up to 500 waypoints per route.

what do you mean by "featured for tracks"? Do I see it correctly that your question is not OSM-related but just about Garmin's device features?

@SomeoneElse I've downloaded from http://garmin.openstreetmap.nl using Generic Routable (new style) option

No thats not possible with the Garmin Etrex, no matter what map you use, this device simply doesn't have turn by turn navigation for tracks

BTW why do you use in the routing function so many points? Maybe better try the openfietsmap (bicycle) from http://garmin.openstreetmap.nl for cycling

Hmm, I think openmtbmap very successfully offers Garmin maps which allow routing with turn-by-turn instructions over tracks/paths for a wide range of devices: https://openmtbmap.org/. Certainly I usually use the All-in-One style for routing by foot with no problems.

SK53, please do not confuse a Garmin "Track" with path or track on OSM. What Garmin called a track is a breadcrumb trail of a route that has been recorded or created on the computer.

Try to convert your track to a route, e.g. by using gpsbabel. For routes your Garmin device will provide turn by turn navigation. However calculating a 200 km route on a Garmin Etrex will take ages, better split up the track into several sections. And try to reduce the number of points per route, gpsbabel can also help you with that.
