Abstract

According to one embodiment, an electronic device, for example, a portable electronic device such as a cellular telephone, a portable navigation device, a personal digital assistant (“PDA”), or an MP3 player, includes a GPS receiver configured to receive GPS coordinates. The GPS coordinates are sent to a CPU that is configured to retrieve location-based information from, for example, a memory device or a cellular module in the electronic device. An FM transmitter module is configured to encode and transmit the location-based information as encoded text, for example encoded RDS text, to an FM receiver in a vehicle. The RDS text can then be displayed on a display panel of the FM receiver. In addition to the encoded RDS text, audio signals from the FM transmitter module can be transmitted to the FM receiver for broadcast by a speaker of the FM receiver contemporaneously with the display of the RDS text.

Claims

1. An electronic device for transmitting location-based information corresponding to GPS coordinates of said electronic device to an FM receiver, said electronic device comprising:

a GPS receiver configured to receive said GPS coordinates;

a CPU configured to retrieve said location-based information corresponding to said GPS coordinates;

an FM transmitter module configured to encode and transmit said location-based information as encoded text.

2. The electronic device of claim 1 wherein said encoded text is an encoded RDS text.

3. The electronic device of claim 1 wherein said electronic device is a portable electronic device.

4. The electronic device of claim 1 wherein said electronic device is utilized to transmit said encoded text to an FM receiver installed in a vehicle.

5. The electronic device of claim 1 wherein said CPU is configured to retrieve said location-based information from a memory device coupled to said CPU.

6. The electronic device of claim 1 wherein said CPU is configured to retrieve said location-based information from a cellular module coupled to said CPU.

7. The electronic device of claim 1 wherein said FM transmitter module is further configured to transmit said location-based information as audio signals.

8. The electronic device of claim 7 wherein said CPU is configured to generate said audio signals by using a text-to-speech algorithm.

9. The electronic device of claim 7 wherein said electronic device is utilized to transmit said audio signals to an FM receiver installed in a vehicle.

10. The electronic device of claim 9 wherein said audio signals are broadcast by a speaker of said FM receiver in said vehicle.

11. The electronic device of claim 3 wherein said portable electronic device is selected from the group consisting of a cellular telephone, a portable navigation device, a personal digital assistant (“

PDA”

), and an MP3 player.

12. The electronic device of claim 4 wherein said FM receiver comprises an FM tuner module coupled to an RDS decoder.

13. The electronic device of claim 4 wherein said FM receiver comprises a display panel capable for displaying RDS text.

14. The electronic device of claim 1 wherein said location-based information includes driving directions.

15. The electronic device of claim 1 wherein said location-based information includes street address of a destination of interest to a user of said electronic device.

16. A portable electronic device for transmitting location-based information corresponding to GPS coordinates of said portable electronic device to an FM receiver in a vehicle, said portable electronic device comprising:

a GPS receiver configured to receive said GPS coordinates;

a CPU configured to retrieve said location-based information corresponding to said GPS coordinates;

an FM transmitter module configured to encode and transmit said location-based information as encoded text for displaying by a display panel of said FM receiver and as audio signals for broadcasting by a speaker of said FM receiver.

17. The portable electronic device of claim 16 wherein said encoded text is an encoded RDS text.

18. The portable electronic device of claim 16 wherein said CPU is configured to retrieve said location-based information from a memory device coupled to said CPU.
