You should now see yourself off the coast of Africa in the Default position set for tracking pages. However you will now be able to see this icon that lets you add a manual gps location.
Click on it to add your current GPS co-ordinates and time. Select NOW for the current time. Then select Save Point.
It will then notify that you have a Tracking Point pending upload/download.
Do another Download the same as last time, and your Tracking point will be uploaded and syncronised with the server. Your tracking page will now reflect your updated position for friends and family to see.
