Point of Interest (POI) Download
The POI Download feature allows the user to request a destination download to their vehicle.
Downloads can be initiated via the TSP operator or a website that offers a destination download
option. TCU receives a message requesting POI information. The TCU will then import the
destination information and report back to the TSP.

3 Handsfree Telephone (Bluetooth) Features
3.1 Product Description
The TCU provides hands-free calling in the vehicle via the short-range wireless radio frequency
communications protocol known as Bluetooth. Integrated into the vehicle audio systems and active on
the data bus, the TCU provides the primary human interface functions to both telephone and installed
audio systems when operating in the hands-free mode. The TCU includes the speech recognition
engine and defined voice tree enabling the voice commanded operation of the system. Primary Hands-
Free Telephone commands may also be initiated via switches provided on the steering wheel and Point
of Interest selection screens via the Navi touch screen display.

The transfer of stored cellular phone book entries to the TCU (Phone Book Access Push) and the
transfer of the complete cellular phone book to the navigation unit upon request (Phone Book Access
Pull) are accomplished via the Hands Free Link/Navi Communications.

3.2 Connection Management
Connection Management refers to all the processes related to managing a mobile device (phone or
audio player) including pairing device(s), deleting device(s), and managing connections to paired
Bluetooth device(s).

3.2.1 Pairing
The TCU supports two methods to pair a device. The first method, Legacy, requires the user to enter a
pre-defined 4-digit pairing code. The second method enables a user to pair a device without entering a
pairing code. This method is called “Secure Simple Pairing”. There are some phones that require a 4-
digit pairing code before they will begin communicating with the TCU to initiate pairing. As a result
the TCU will provide pairing code instructions to the user in some cases when it may not be necessary.
This will be described in detail under Passive Pairing, below.

The TCU system can add Mobile Devices, one device at a time. Prior to pairing a new device, the
TCU will disconnect from all currently connected devices to prevent unwanted interruptions during
the pairing process.

If the device supports BT version 2.1 or greater, the TCU will determine the security level available on
the Mobile Device. If the device supports BT version 2.0 or earlier, the TCU will initiate the Legacy

4-Digit Code Pairing (Legacy Pairing):
When adding a device to the TCU, the user may enter a pairing code on the mobile device (only if the
device does not support Bluetooth 2.1). The TCU has a pre-defined pairing code so that the user does
not have to enter a pairing code on the TCU at the time of pairing. During the pairing function, the
TCU’s pairing code will be displayed on the in-vehicle display. The user will be able to change the
