DESCRIPTION

The telematics system provides the vehicle owner with information and services that can be accessed in ease over a secure connection using the NissanConnect Services APP (Apple/Android).

NOTE: In order to use NissanConnect Services; Vehicle Owners must subscribe to it separately.

TCU (Telematics Communication Unit) equipped with a radio communication terminal communicates with the information center (NissanConnect Services Data Center) via radio waves for receiving NissanConnect Services
Available services via the telematics system are defined as NissanConnect Services.
TCU integrates a wireless communication terminal and is connected to the telematics antenna that allows it to send/receives data with the NissanConnect Services App using packet communication *1 and SMS *2.
NOTE:
- *1: Packet communication is the communication method that sends/receives data in a small packets with information. Divided data is referred to as a packet and the communication line can be efficiently used.
- *2: SMS stands for Short Message Service. It is also referred to as Text Messaging, Short Mail, etc. It is the service that performs text based message communication.
The telematics system interacts with the NissanConnect Connection Data Center using GPS and GSM/GPRS technologies. The TCU can send messages to and receive commands from the NissanConnect Services Data Center. This allows the NissanConnect Services Data Center to monitor the vehicle and obtain actual position coordinates and automatically detected events, as well as initiate certain services from outside the vehicle. In addition, the vehicle operator can initiate services from inside the vehicle.
Telematics antenna, telematics switch and microphone are connected to the TCU via Hardware (Physical connection).
