You need to download a OSM map that has contours included or a transparent overlay with elevation contours.  Most of the popular OSM sites have one of these options.

The only osm site I use is the  Garmin.nl site but it does not have a contour map option available.
I updated my maps 2 years ago and lost the contours.
 any thoughts of which map to download?
Thanks

HI Ian, there's a contour overlay available here http://garmin.openstreetmap.nl/ and I'm pretty certain that these maps contain contours http://www.openfietsmap.nl/downloads/europe as do these https://www.velomap.org/download/odbl/

Best to use an overlay if your GPS accepts multiple map files.  That way you can update your road maps any way you like and the contours will still be there.  The one I've got has contours for all the UK at 10m intervals but it's a pretty big file - about 100Mb.  I also have an overlay for France and borders, and the Swiss/Italian Alps but that is spaced at 20m intervals (which is actually better in mountainous areas) and that's about 150Mb.
It's not dark yet but it's getting there.

That page lists a contour overlay, but you can't actually select that option. I think it is planned to add it, but hasn't happened yet.

Does anyone know if you can overlay the contours in Basecamp?  As they'd be a more useful overlay for me when planning.
