A = Hardwired; N = Medium Speed CAN (controller area network) bus; O = LIN bus; P = MOST ring
PRINCIPLES OF OPERATION
Primary user control of the phone system is via the Touch-screen and JaguarVoice control switch. Selection of 'phone/comms' on the Touch-screen home menu sends a control signal to the telephone control unit on the MOST (media orientated systems transport) ring, opening the phone submenu options.
When making an outgoing phone call using the JaguarVoice function the ICM (information control module) processes the analogue signal from the switch into a digital signal. The digital signal is passed from the ICM (information control module) onto the MOST (media orientated systems transport) system to the JaguarVoice control unit which is integral with the navigation computer.
The navigation computer sends an instruction via MOST (media orientated systems transport) to the IAM (integrated audio module) to turn on the microphone facility.
The voice command signals are relayed from the IAM (integrated audio module) via the MOST (media orientated systems transport) ring to the navigation computer for processing.
The processed voice command is relayed on the MOST (media orientated systems transport) ring from the navigation computer to the phone control module.
Speech output information is transferred from the phone control module via the Bluetooth(R) connection to the cell phone.
Incoming calls are received from the Bluetooth(R) phone by the phone control module. The information is processed by the phone control module and transferred on the MOST (media orientated systems transport) ring to the power amplifier or IAM (integrated audio module) for audio output through the vehicle's audio speaker system.
A number of responses by the telephone and voice systems are reinforced by messages appearing in the instrument cluster message center display. Information is relayed to the message center from the phone control module and navigation computer on the MOST (media orientated systems transport) ring to the ICM (information control module).
The ICM (information control module) is the gateway from the MOST (media orientated systems transport) ring to the medium speed CAN (controller area network). The ICM (information control module) transfers the message center information onto the medium speed CAN (controller area network) which is received and processed for display on the instrument cluster message center.
Users can pair & dock their handset using their phone or the touch screen. If there is no phone already docked with the system, a user can use their phone to search for Bluetooth Devices. If the vehicles Bluetooth system has been successfully discovered, the phone will display "Jaguar" as a device to pair & connect to. Using this method requires the user to enter the Jaguar PIN of 1313. Alternatively, after accessing the phone menu from the Touch-screen home menu, selecting 'Search New' searches for the Bluetooth(R) enabled handsets within range, displays their identities on screen, and allows the user to pair and dock the phone ready for use, using a random four-digit security code displayed on screen. The system will normally try to dock (automatically) to the last phone docked, but if a different Bluetooth(R) enabled phone enters the car it will become available on the screen's list of handsets once the search has been completed.
Once a phone is paired and docked a digit dial screen is displayed, including phonebook options. With a Bluetooth(R) compatible handset and software version there is the option, through the settings menu, to automatically download the contents of the handset's phonebook to the vehicle system. Because there is no industry standard for arranging the phonebook, the downloaded lists from individual handsets may vary.
Cell phone handset manufacturers continually update hardware and software to standard specifications laid down by the Bluetooth(R) Special Interest Group (SIG), which defined how Bluetooth(R) would work in an automotive environment. However, because different makes and models may use different software, not all handsets are fully compatible with Jaguar, but through testing individual handset models Jaguar has produced a list of compatible handsets and the appropriate software version for Jaguar Bluetooth(R) connectivity. Referral to the list also describes how to check the software version of each individual cell phone manufacturer. This list must be consulted by users, sales & service teams to confirm whether customer's handsets are compatible or not.
Jaguar is continually validating compatible handset and software combinations. The most up-to-date compatibility list will always be available on-line from Jaguar.
NOTE:
To achieve full Bluetooth(R) handset functionality it is crucial that the phone software level matches the version detailed in the list of compatible handsets.
The upgraded hands free profile of this system allows the display of the network signal strength, network operator and phone battery level indication on the vehicle display. Also, if applicable, the phone handset will show a "car" or "headset" symbol to indicate it is in handsfree profile.
BLUETOOTH(R)
Bluetooth(R) is a short-range RF (radio frequency) technology that operates at 2.4 GHz and is capable of transmitting voice and data wirelessly. The effective range of Bluetooth(R) devices is 32 feet (10 meters) with a data transfer rate of 1 Mbps.
Bluetooth(R) is essentially a wireless connection which operates with the user's own mobile handset, does not have to be fixed into the car and is designed to function without an external aerial. The handset can be located anywhere within the cabin, even in a bag, or jacket pocket. It could work from the luggage compartment, although the signal could be compromised. The handset can be charged from the 12 volt power socket or USB (if supported) while in use.
Touch-Screen
The Touch-screen communicates with the telephone control module on the MOST (media orientated systems transport) ring and provides the primary user interface and display of the phone system.
The following functions are available on the phone menu:
- Digit dial
- Phone book
- Last ten calls (made, received, missed)
- Voicemail
Steering Wheel Controls
Additional control of the phone system is available in the form of steering wheel mounted switches which are located on the left hand side of the steering wheel. The switches provide for volume adjustment, scroll up/down to next/previous memory location, instrument cluster message center phonebook access and finally JaguarVoice/call control.
The steering wheel control switches are hardwired through the clock spring to the ICM (information control module). The ICM (information control module) processes the analogue signals from the switches into digital signals. The digital signals are then passed from the ICM (information control module) onto the MOST (media orientated systems transport) system for control unit processing and operation of the requested functions.
JaguarVoice
JaguarVoice enables activation of several voice activated functions of the infotainment and climate control systems without the need to touch any controls manually. The following systems include JaguarVoice functionality;
- Navigation system
- Phone system
- Climate control system
- Vehicle display system
- Vehicle notepad
The 'notepad' facility allows voice notes to be recorded. Nametags for phone dialing and navigation locations allow the system to be personalized and there is a help and tutorial function to provide advice on using the system.
The system allows the vehicle user to concentrate fully on driving the vehicle, without any need to divert their eyes from the road ahead in order to check information read outs on the vehicle instrument panel information units. The voice control system also feeds back audible information to the vehicle user.
JaguarVoice is a key component of the phone system, allowing hands free control and use of the Bluetooth(R) enabled phone.
The system is controlled by the voice button on the left hand side of the steering wheel. Voice commands are picked by the dedicated microphone. When giving a voice command audible feedback will be heard through the vehicle's audio speakers. Received call voice/speech is also broadcast on the vehicle audio speaker system. All speakers are used for voice/speech output with the exception of the front center speaker (only fitted on the Bowers & Wilkins 440W Surround Sound System) due to echo return picked up by the microphone.
Efficient operation of JaguarVoice is reliant on the user understanding some of the following basic operating conditions;
- Face forwards, sitting in a normal driving position
- After pressing the voice button, always wait for the end of the audible tone before speaking.
- Speak naturally, as if you were talking to a passenger or on the phone without pausing between words
- When the system asks for more information, always wait for the end of the tone before responding
- Always say numbers correctly
- Excessive noise, for example while driving with windows open, may cause voice command mis-recognition. If it is too noisy to use the phone, it is likely that voice commands will not be recognized
Most accents are understood without difficulty, but if the system does not recognize the command it will respond "SORRY" and allow two more attempts to say the command.
Voice feedback is given in the same language as the command recognition. It is possible to change the language of the speech control system.
