1. A road finishing machine comprising: a chassis; a screed for laying a paving layer on a subsoil, the screed being associated with the chassis; a temperature sensor fixed to the chassis and directable to the subsoil such that the temperature sensor may detect a temperature of at least a region of the subsoil which is located in front of the screed, as seen in the direction of travel of the road finishing machine; a display unit configured to display the detected temperature of the region of the subsoil to an operator; a control unit, the temperature sensor being connected to the control unit for forwarding the detected temperature of the region of the subsoil; and a receiver with an antenna embodied to receive positional data and forward the positional data to the control unit; wherein the control unit is embodied to georeference the detected temperature of the region of the subsoil with the positional data, the road finishing machine is configured to use the georeferenced temperature for controlling at least one paving parameter, and the road finishing machine is further configured to display to the operator when the detected temperature of the region of the subsoil reaches and/or falls below a predetermined minimum temperature.
