Cellular Phone: Description and Operation

Cellular Phone

COMPONENT LOCATION









INTRODUCTION
The cellular phone system is based on using the customers own Bluetooth capable handset with the vehicle Information and Entertainment system.

NOTE:
There is no physical connection (cradle) between the phone handset and the Telephone Control Module. Communications between the two components are purely Bluetooth. This can limit the available functions dependant on the handset used.
The cellular phone system comprises the following components:
- Telephone Control Module
- Microphone
- Bluetooth antenna
The system allows the driver to send, receive and end phone calls using the Touch Screen Display (TSD), steering wheel switches and voice recognition system.
Phone dialing is achieved using one of the following methods:
- Dialing a number using the TSD keypad
- Selecting a number from the handsets phonebook
- Selecting from the handsets 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 ring. This allows audio and control signals to be routed to and from the Telephone Control Module.
