The Satellite Radio Control Module (SRCM) is located below the front right seat. The SRCM is secured to a mounting brackets and secured with flanged nuts.
The SCRM is a dedicated tuner which is controlled by the IAM on the MOST ring. The tuner filters the signals from the satellite radio antenna located in the roof pod or sigma pod. Information is transmitted on the MOST ring and processed by the IAM. The processed information is sent out to the audio amplifier module and broadcast through the speaker system.
The digital radio format adopted for NAS vehicles is satellite radio operating in the S-Band frequency range (2.3 GHz). Satellite Digital Audio Radio Service (SDARS) service provider 'SiriusXM' transmit a signal from their up-link facility (which is the original point of transmission of data, voice or other information through an antenna system) to a satellite where the signal is then down linked to both the terrestrial repeater network and the individual satellite radio system in the vehicle. The SCRM switches between the satellite signal and the repeater network signal depending on the strength of the signal at any given time.
The SiriusXM satellite system comprises:
The SiriusXM satellite radio system uses three satellites on an inclined elliptical orbit. This ensures that each satellite spends approximately 16 hours a day over the continent of North America, with at least one satellite over the country at any one time.
The satellites beam their signals down to the ground where the signal is picked up by receivers or is transmitted to repeater stations to cover built up areas where the signal is obscured. The satellite service comprises over 100 channels of digital entertainment which is provided by subscription requiring a monthly payment. In order to obtain a subscription, the satellite radio control module ID number will need to be retrieved from the module.
This is achieved as follows:
If no subscription has been taken, the TS will display the SiriusXM telephone number. To subscribe to SiriusXM use the displayed phone this number. The user will need payment details, the SiriusXM ID number and details of the required package.
The satellite radio function is accessed by pressing the SAT Radio icon on the TS. This allows the user access to another bank of possible favourites, with the option to store 6 favourites on each of SAT 1, SAT 2 and SAT 3.
Operation of the satellite radio system is the same as the radio operations with selections made through the TS to access and navigate the system functions.
No configuration procedure is required if the SRCM is replaced. Calibration of the SRCM using approved Land Rover diagnostic equipment enables updates to be downloaded as new technology becomes available or any fault concerns require software updates.
HD RADIO - NAS ONLY
HD Radio technology is a free digital radio format broadcast available in the NAS market and may become available for other markets in the future.
HD Radio digital broadcasts are transmitted alongside the analogue AM and FM signals by stations broadcasting HD Radio signals. HD Radio technology has the ability to deliver improved sound quality and content to the listener, blending between analogue and a digital audio streams of the primary station and delivering extra multicast stations on the same frequency.
The HD Radio receiver is integrated into the AM / FM tuner on NAS variants of the AHU and the IAM.
ANTENNAS
AM, FM, digital radio, satellite radio, Television (TV) and Fuel Fired Booster Heater (FFBH) antennas are located in the roof pod and rear quarter windows. For additional information refer to Antennas.
SPEAKERS
The number, location and specification of the speakers in the vehicle differs depending on the level of audio system fitted.
For details of the speaker systems, refer to the 'Speakers' section.
ADVANCED VOICE CONTROL
The advanced voice system provides the driver with the option of voice control for a range of supported functions. The following systems include Voice functionality:
For details of voice control, refer to the 'Voice Control' section.
