Abstract

A navigation apparatus (10) configured for removably coupling with and providing navigational capabilities to a portable, handheld computing device (12). The navigation apparatus (10) includes a navigation receiver (26) for receiving navigation signals from a plurality of sources; a processor (24) coupled with the navigation receiver (26) for determining a location of the navigation apparatus (10) as a function of the received navigation signals; and an interface/connector (44). The interface/connector (44) is either a Secure Digital slot connector or a Compact Flash slot connector. Location data stored in the navigation apparatus (10) and data representative of the location determined by the navigation apparatus (10) may be delivered from the processor (24) to the handheld computing device (12) so that it may be displayed and used by a user of the device (12).

Claims

1. A navigation apparatus configured for voice communication with a user, the navigation apparatus comprising:

a navigation receiver for receiving navigation signals from a plurality of sources;

a microphone for detecting voice commands from the user;

a processor coupled with the navigation receiver and the microphone, the processor adapted to determine a location of the navigation apparatus as a function of the received navigation signals, to interpret the voice commands communicated by the microphone, to generate routing instructions based on the voice commands, and to communicate the routing instructions in an electronic audio signal;

a speaker for receiving the electronic audio signal from the processor and for converting the signal into audible instructions; and

an expansion slot coupled with the processor for removably coupling with an external memory cartridge which has location data stored thereon, wherein the processor may access the location data from the external memory cartridge via the expansion slot.

2. The navigation apparatus as set forth in claim 1, wherein the expansion slot is selected from the group consisting of a Secure Digital slot connector and a Compact Flash slot connector.

3. A navigation apparatus configured for coupling with and providing navigational capabilities to a portable, handheld computing device, the navigation apparatus comprising:

a navigation receiver for receiving navigation signals from a plurality of sources;

a processor coupled with the navigation receiver adapted to determine a location of the navigation apparatus as a function of the received navigation signals, to interpret voice commands communicated by a user of the handheld computing device, to generate routing instructions based on the voice commands, and to communicate the routing instructions to the computing device in an electronic audio signal;

a memory accessible by the processor for storing location data and voice communication data; and

a connector coupled with the processor for removably connecting with a corresponding expansion slot on the handheld computing device to allow the handheld computing device to communicate the voice commands to the processor and to allow the processor to communicate the routing instructions to the handheld computing device.

4. The navigation apparatus as set forth in claim 3, further including a microphone for detecting the voice commands and communicating the voice commands to the processor.

5. The navigation apparatus as set forth in claim 4, further including a speaker for receiving the electronic audio signal from the processor and for converting the signal into voice instructions.

6. The navigation apparatus as set forth in claim 5, wherein the processor is further adapted to detect when the handheld computing device is capable of voice communications, receive the voice commands and communicate the routing instructions to the handheld computing device if it is capable of voice communications, and receive the voice commands from the microphone and communicate the routing instructions to the speaker if the handheld computing device is not capable of voice communications.

7. The navigation apparatus as set forth in claim 5, wherein the connector is selected from the group consisting of a Secure Digital slot connector and a Compact Flash slot connector.

8. The navigation apparatus as set forth in claim 3, wherein the connector is further adapted to allow the location data and the voice communication data stored in the memory and data representative of the location of the apparatus to be delivered from the processor of the navigation apparatus to the handheld computing device.

9. A navigation apparatus configured for coupling with and providing navigational capabilities to a portable, handheld computing device, the navigation apparatus comprising:

a navigation receiver for receiving navigation signals from a plurality of sources;

a microphone for detecting voice commands and communicating the voice commands in an electronic signal;

a processor coupled with the navigation receiver and adapted to determine a location of the navigation apparatus as a function of the received navigation signals, to interpret voice commands communicated by the handheld computing device or by the microphone, to generate routing instructions based on the voice commands, and to communicate the routing instructions to the speaker in an electronic audio signal;

a speaker for receiving the electronic audio signal and for converting the signal into audible instructions;

a memory accessible by the processor for storing location data and verbal communication data; and

a connector coupled with the processor and selected from the group consisting of a Secure Digital slot connector and a Compact Flash slot connector for removably connecting with a corresponding expansion slot on the handheld computing device so that the location data stored in the memory and data representative of the location of the apparatus may be delivered from the processor of the navigation apparatus to the handheld computing device.

10. The navigation apparatus as set forth in claim 9, wherein the processor is further adapted to detect when the handheld computing device is capable of voice communications, receive the voice commands and communicate the routing instructions to the handheld computing device if it is capable of voice communications, and receive the voice commands from the microphone and communicate the routing instructions to the speaker if the handheld computing device is not capable of voice communications.

11. The navigation apparatus as set forth in claim 9, wherein the audible instructions are voice instructions.

12. The navigation apparatus as set forth in claim 9, wherein the handheld computing device is a cellular phone.
