Kind of bike related as this is for use on my bike.
I’ve bought Garmin and am trying to install OSM on it.
I downloaded a map from http://talkytoaster.co.uk/maps/
renamed it gmapsupp.img created a file on the SD card called Garmin, place the img file in this folder.
The GarminDevice.xml file says
<Name>SupplementalMaps</Name><File><Specification><Identifier>IMG</Identifier></Specification><Location><Path>Garmin</Path><BaseName>gmapsupp</BaseName><FileExtension>img</FileExtension></Location>
Which to me tells me I am putting it in the correct place.
When I am in map mode and I go setup map the options I get are only the base maps.
What am I doing wrong!!
