Abstract
An in-vehicle system comprises a location unit, a frequency selection unit, and a receiving unit. Frequency tuning data is loaded into the selection unit. The frequency tuning data includes a radio signal reception area for each unique frequency in the tuning data. The location unit determines the system location and passes the location information to the frequency selection unit. The selection unit selects tuning data for a particular frequency having a signal reception area that encompasses the present vehicle location, and passes the selected data to the receiving unit. The receiving unit uses the selected tuning data to tune the radio signal.
