Click the GridRef, and a new window will open up showing it on streetmap.co.uk
To set up your satnav, use the "convert" link below the map to get Lat/Long or the nearest postcode.
[ NB: Firefox browser version 74.0 has blocked security method TLS1, used by streetmap.co.uk, so that the maps can't be accessed. At the moment Firefox provides a button to allow it, but they threaten to remove it in the future. However I believe it will always be possible to allow TLS1 by going to 'about:config', search for 'security.tls.version.min', and edit it from 3 to 1. I would guess that streetmap might change in the future if Firefox users complain.
At time of writing, Chrome and Edge browsers are both version 80 and do not have the restriction. Dave W ]
