In automatic operation GumsBleau displays a description to reach the parking (cars) and the meeting point for the next climbing outing on the boulders of the Fontainebleau forest of the University Group of Mountain and Ski (GUMS-Paris) . A button allows you to launch a car guide app to the closest car park to the rocks. Another button launches a map application opening a detailed topographic map showing a marker on the position of the appointment.

Another feature of GumsBleau allows to obtain the same information by choosing as destination one of the appointments among the 50 climbing blocks that the GUMS uses in the forest of Fontainebleau.
