You are not logged in to Jowett Internet Services. Not only do you need to be logged in, but you also need to have requested access to JIS on your User Control Panel profile and also be a member of the relevant club whose members' map you are trying to view.
Members have access to an interactive map (see below) that enables them to locate members to see what help they can offer or may require. This helps us organize such things as ‘Get a Jowett on the road’ days or locate members on a smartphone when travelling. The codes say whether members have spares for particular cars or can offer help in case of breakdown.
