OVERVIEW

The cellular phone system uses the customers own Bluetooth capable mobile phone in conjunction with the vehicle information and entertainment system. The system is controlled by the Audio Head Unit (AHU) or the Integrated Audio Module (IAM) depending on vehicle specification. Both the AHU and the IAM have a Bluetooth antenna incorporated into the unit.

Mobile phones must be paired with the AHU or the IAM, requiring the input of a 4 digit Personal Identification Number (PIN) before they can be used with the vehicle system.

NOTE:

PIN's can be as long as 16 digits, however, 4 digits is recommended

Once paired, any mobile phone can be 'docked' to the vehicle without reentering the PIN. In addition, the last connected mobile phone will dock automatically next time it is present in the vehicle and the ignition is in power mode 6 (ignition on) or power mode 7 (engine running).

Bluetooth wireless technology allows electronic devices to communicate wirelessly through a short-range Radio Frequency (RF) network. Bluetooth wireless technology can simultaneously handle data and voice transmissions which allows the vehicle's Bluetooth telephone system to provide hands free operation of the users Bluetooth telephone.

The Land Rover Bluetooth system supports Bluetooth Hands-Free Profile (HFP), Advanced Audio Distribution Profile (A2DP) and Audio Video Remote Control Profile (AVRCP).

Bluetooth pairing of new mobile phones is achieved by selection of 'Search New' from the device list screen. The system has two pairing modes; 'vehicle to device' and 'device to vehicle'. Up to 10 Bluetooth devices can be paired to the vehicle.

The system allows the driver to make, receive and end phone calls using the Touch Screen (TS) or the left steering wheel switchpack or voice control (where specified).

The cellular phone system incorporates a new Land Rover feature which enables the driver to access their mobile phone applications (Apps) via the TS. When driving, the driver can access phone, navigation, music and voice functions (including email and SMS if 'Text to Speech' is used); when stationary, all applications except video can be operated. The TS enables TS functions, as found on the latest mobile phones. The system is compatible with iPhone 5 and later (not earlier OS) and Android mobile phones using Android 4 or later.

On vehicles with the InControl Touch Plus and InControl Touch Plus with Meridian Surround audio systems, the user interface of the mobile phone is displayed on the vehicle TS through a Telephone Interface Module (TIM).

The TIM reads the mobile phone data, displaying it on the vehicle TS. The TIM is compatible for both Apple and Android mobile phones, enabling the TIM to have a standard connection to both devices by having a single data transfer USB port.

On vehicles with the InControl Touch audio systems, the user interface of the mobile phone is displayed on the vehicle TS through software integral with the Audio Head Unit (AHU). The AHU integral software reads the mobile phone data, displaying it on the vehicle TS. The AHU software is compatible for both Apple and Android mobile phones, enabling the AHU to have a standard connection to both devices by having a single data transfer USB port.

In order to present the user interface of a mobile phone touch screen onto the vehicle Touch Screen, a 'Launcher App' must be installed on the mobile phone to enable the transfer of the user interface from the mobile phone to the vehicle Touch Screen. The mobile phone must also be connected via the applicable Universal Serial Bus (USB) port in the portable audio interface panel.

The InControl 'mobile phone App' allows the user to check vehicle related information, for example; fuel level, locating the vehicle in a car park and download journey logs using their Apple or Android mobile phone App.

The InControl mobile phone App is downloaded from the Apple App Store or Google Play. The mobile phone App can be updated on a regular basis, adding new features and services as they become available. The Land Rover InControl App has three main areas; Remote, Secure and WiFi, which offer options providing safety, security, connectivity and convenience functions.

The InControl App uses the vehicle Telematics system and WiFi for connectivity.
