1. A method of configuring a tuner, comprising the steps of:
- scanning at least one range of radio frequencies;
measuring a signal quality metric for each of a plurality of the frequencies; and
selecting a set of operational frequencies for the tuner, the set of operational frequencies corresponding to a radio frequency convention in a particular region of the world, said selecting being dependent upon the measuring step, the selecting step including the substeps of;
determining in which particular region of the world the tuner is most likely disposed, the set of selected operational frequencies corresponding to the particular region of the world in which the tuner is most likely disposed;
informing a user of which particular region of the world the tuner is most likely disposed; and
enabling the user to select another set of operational frequencies and thereby override the set of operational frequencies selected in correspondence with the particular region of the world in which the tuner is most likely disposed.

8. A method of configuring a tuner, comprising the steps of:
-
scanning a first range of one of FM radio frequencies and AM radio frequencies; measuring a first signal quality metric for each of a plurality of the radio frequencies in the first range; scanning a selected second range of an other of FM radio frequencies and AM radio frequencies; measuring a second signal quality metric for each of a plurality of the radio frequencies in the second range; performing an RDS/RBDS synchronization check on each of the frequencies that have a measured signal quality metric exceeding a threshold value, the performing step being performed after at least one of the measuring steps; and selecting a set of operational FM frequencies for the tuner and a set of operational AM frequencies for the tuner, the set of operational FM frequencies and the set of operational AM frequencies corresponding to a radio frequency convention in a particular region of the world, the selecting being dependent upon each of the measuring steps and upon the performing step. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method of configuring a radio, comprising the steps of:
-
scanning at least one range of radio frequencies; measuring a signal quality metric for each of a plurality of the frequencies; selecting a set of operational frequencies for a tuner of the radio, the set of operational frequencies corresponding to a radio frequency convention in a particular region of the world, the selecting being dependent upon the measuring step; and defining at least one function for a corresponding user interface control associated with the radio, the defining being dependent upon at least one of the selected set of operational frequencies and the corresponding radio frequency convention. - View Dependent Claims (16, 17, 18, 19, 20)
