ABSTRACT:
A data processing device for providing data related to the categories of services available at locations along a highway in response to operator input is disclosed. The device includes a memory, a keyboard for entering input data identifying a desired service and an origin position into the memory. The input data is compressed before it is stored in the memory. The memory stores predetermined data in a compressed form related to the categories of services available at locations along the highway. The device also includes a microprocessor for retrieving from the memory the predetermined data which is a function of the input data. The microprocessor expands the retrieved compressed data into an operator readable form and provides the expanded data to a display for displaying the expanded retrieved data such as restaurants, gas stations, motels, or other services along the highway.
