Accessories and Optional Equipment: Description and Operation

The audio system on the PT consists of a radio that communicates over the PCI Bus. Each radio system comes equipped with a standard premium 6 speaker system. The speakers are located in the instrument panel, the front doors and the rear "D" pillars. The instrument panel speakers are a tweeter type speaker for high frequency. The front door speakers are a woofer/midrange type speaker. The rear "D" pillar speakers are a full range type speaker. If one of the speaker circuits experiences a short, the other speakers on that channel will also shut down until the circuit is repaired. The radio will also set a trouble code, which the DRBIII(R) can display.

NAVIGATION RADIO
The optional navigation radio system receives GPS signals from up to eight satellites to display the position and direction of the vehicle. Map information is supplied through a DVD-ROM. An electronic gyrosensor and the vehicle's speed sensor enable the system to display the present vehicle position even in locations where GPS signals may be blocked.

When a destination is selected, the navigation system uses information from the map to quickly calculate a route. As the vehicle is driven along the chosen route, the operator is guided with pictorial displays and voice prompts. For complete operating instructions, refer to the manual included with the vehicle.

SATELLITE RADIO (SDARS)
To use the satellite radio, the radio must be in satellite mode. The satellite antenna must have an unobstructed view of the satellite. The vehicle must be outside to receive proper reception. Poor reception may be experienced in large down town areas where tall buildings are present. The satellite network is still under development, and this could be the cause of poor reception in certain areas. Use a known good system to verify network performance in these areas.

Once in satellite mode, the radio head is used to change stations. The Radio must be in Satellite mode to communicate to the Satellite Receiver Module with the DRBIII(R). The Radio head communicates to the Satellite Receiver Module via the PCI bus and the private Audio bus. The Audio bus functions just like the PCI bus, but its use is restricted to the Radio and the Satellite Receiver Module.

The Satellite Receiver Module processes signals it receives from the satellite antenna. That information is then sent to the Radio where it is processed and sent out to the speakers. The Satellite Receiver Module has the ability to detect and store fault code information, which may be retrieved with the DRBIII(R).
