A method and an onboard unit for levying tolls for a vehicle, with a satellite navigation receiver for generating position fixes, a memory for recording geoobjects, a radio interface, and a processor that generates toll data from a geographical comparison of position fixes with geoobjects in a digital map and transmits this data via the radio interface. The memory has an index memory region for an index tree for geoobjects, a first static object memory region for a primary list with geoobjects, and a second object memory region, for a secondary list with geoobjects, wherein at least one leaf of the index tree contains a reference to a secondary list, and wherein the processor is configured, upon accessing a geoobject via a leaf, when this contains a reference.to a secondary list, to use the secondary list as a matter of priority before the primary list.
