Abstract
Methods, systems, and computer program products are disclosed for indicating a return route in a mobile device. A location identifier representing an intermediate point along a route is received and is independent of global positioning system information. A direction of travel is associated with the location identifier. Directional instructions indicating a return route passing through the intermediate point are determined. The directional instructions are determined based on the location identifier and the associated direction of travel without reference to a mapping database and independent of global positioning system information. The directional instructions are then presented.
