a control unit configured to select and tune between the traffic message channel and the analog and digital radio programs;
a recording unit capable of recording a radio program at predetermined times; and
an audio signal output unit configured so as to play back recorded radio programs at tires determined by the user.
12. The portable personal navigation device of claim 11 , further comprising:
a position determination unit determining a position of the portable personal navigation device;
wherein the first radio receiver is configured so as to tune to a radio channel in accordance with position information supplied by the position determination unit.
13. The portable personal navigation device of claim 12 , further comprising a memory for storing radio channel frequency information in association with position information.
14. A portable personal navigation device comprising:
a navigation unit configured to determine a location of the portable personal navigation device, calculate a route to a predetermined destination, and display navigational information to a user;
a multiple band receiver for radio waves configured to receive analog and digital radio programs;
a control unit configured to select and tune between the analog and the digital radio programs;
a second receiver configured so as to receive a traffic message channel while simultaneously receiving the analog and the digital radio programs; and
an output unit for outputting an audio signal configured to play back the radio programs.
15. The portable personal navigation device of claim 14 , further comprising a recording unit capable of recording a radio program at predetermined times.
16. A method of operating a portable personal navigation device, the method comprising the steps of
tuning a multiple band receiver of the portable personal navigation device to a frequency for receiving a radio program;
determining a position with a position determination unit of the portable personal navigation device;
adjusting the frequency for receiving a radio program if the determined position meets a predetermined criterion;
calculating a route to a predetermined destination;
tuning the multiple band receiver to a traffic message channel;
receiving traffic information the traffic message channel that provides information to the position determination unit for calculating the route; and
recalculating the route using the traffic information.
17. The method of claim 16 , wherein the predetermined criterion is whether the determined position is located within a predetermined geographical area.
18. A method of operating a portable personal navigation device, the method comprising the steps of
determining a position with a position determination unit of the portable personal navigation device;
calculating a route to a predetermined destination;
receiving traffic information from a multiple band receiver configured to receive a traffic message channel that provides information to the position determination unit for calculating the route;
recalculating the route using the traffic information;
at predetermined times, tuning the multiple band receiver to an analog radio program and recording the analog radio program using a recording unit; and
at predetermined times, tuning the multiple band receiver to a digital radio program and recording the digital radio program using the recording unit.
19. The method of claim 18 , wherein the position is continuously being determined by the portable personal navigation device while the radio program is being recorded.
20. The method of claim 18 , further comprising the step of providing navigation information to a user of the portable personal navigation device while recording the radio program.
