+===== Upload OpenStreetMap route to the Garmin =====
+There is a fantastic service offered by **[[https://maps.openrouteservice.org/|maps.openrouteservice.org]]**: just choose a **starting** and an **ending point** on the map, add waypoints if required, select **pedestrian** or **car** routing. Then **download the GPX track** that you can **upload** to the Garmin Foretrex.
+I used a serial-to-USB adapter, with **gpsbabel** on GNU/Linux, this is the command line:
+<code>
+gpsbabel -t -i gpx -f Track_cerchiaia-pacini.gpx -o garmin -F /dev/ttyUSB0
+</code>
+Be sure you put the GPS in Garmin mode: //Setup// => //Set interface// => //I/O Format Garmin//.
+===== Upload Google Maps route to the Garmin =====
+Add the following code as a link into your FireFox bookmarks (call it **[[http://www.elsewhere.org/journal/gmaptogpx/|GMapToGPX]]**).
+<code>
+javascript:(function(){var%20script=document.createElement('script');script.src='http://www.elsewhere.org/GMapToGPX/gmaptogpx.js';document.getElementsByTagName('head')[0].appendChild(script);})()
+</code>
+A copy of the JavaScript code is here: **{{gmaptogpx.js.gz|gmaptogpx.js}}**.
+Open Google Maps and obtain driving directions.
+Click on the bookmark.
+It will appear a window. If you want all the points, get the data as a trak. Copy and paste in a document.
+You need to split in files of max 500 trackpoints each, because saved tracks have that limit on the Gramin.
