Cellular Phone: Description and Operation: Overview

Cellular Phone

OVERVIEW
The cellular phone system uses the customers own Bluetooth(R) capable handset in conjunction with the vehicle information and entertainment system. The telephone control module is located under the left-hand front seat, and has a Bluetooth(R) antenna integrated into the unit. Telephone handsets must be paired with the telephone control module, requiring input of a PIN (personal identification number) before they can be used with the vehicle system. Once paired, any phone can be docked to the car without re-entering a PIN (personal identification number). In addition to this, the last connected device will dock automatically the next time it is placed in the vehicle and the ignition is in power mode (ignition on).
The system has the ability to pair and dock telephone handsets from the telephones themselves. By supplying a fixed PIN (personal identification number), a user will be able to use their telephone or other telephone related Bluetooth(R) device and pair with it without using the touch screen. This enables devices such as Blackberry's and other secure PDA's (personal digital assistants) to pair and dock with the vehicle system.
Up to 5 telephone handsets can be paired with the vehicle, but only 1 telephone can be used at a time. The Touch-screen displays phone functionality, including dialing, and (if compatible) the handset's phone book. The Touch-screen also displays the phone's signal strength and battery meter (if supported by the phone). These functions allow the user to view the displays on the Touch-screen and not have to use the handset.

NOTE:
There is no physical connection (cradle) between the phone handset and the telephone control module. Communications between the 2 components are purely Bluetooth(R). This can limit the available functions dependant on the handset used.
The system allows the driver to make, receive and end phone calls using the Touch-screen, steering wheel switches and voice recognition system (if fitted).
Phone dialing is achieved using one of the following methods:
- Dialing a number using the Touch-screen keypad
- Selecting a number from the handsets (automatically or manually downloaded) phonebook on the Touch-screen
- Selecting a number from the handsets (automatically or manually downloaded) phonebook in the instrument cluster message center
- Selecting from the handsets (downloaded) call register, typically the last 10 calls made, received and missed
The telephone control module is connected to the information and entertainment system on the MOST (media oriented systems transport) ring. This allows audio and control signals to be routed to and from the telephone control module.
