Saab 9-3 Audio, Navigation and Telematics (2007-2012)

Detailed description

The entertainment head unit is mounted in the centre of the dashboard. The head unit receives audio and antenna signals from other units in the system. The signals are transmitted on from the unit's outputs to the speakers of the Premium 70 audio system and by I-bus to the amplifiers of the Premium 150, Prestige 300 and Bose® audio systems.

Attachment 8367

The entertainment head unit is an FM/AM receiver with PLL double synthesis tuner for precise station setting, preset to various frequency bands depending on the market. The radio receiver has a memory, which makes it possible to retain selected stations even if battery power is lost. The CD player supports the mp3 format.

The hardware is the same for all markets and is controlled by "end of line programming". If the unit is to be replaced, it must be programmed for the relevant market. Security access from TIS is required to "marry" and "divorce" the audio unit from the car.

Control panel
The control panel is used to select functions. See Audio system operation.

Important
In the service manual the normal handling of the audio system is not dealt with. Detailed information regarding handling can be found in the owner's manual.

Steering wheel controls
There are steering wheel controls for selecting preset stations (2), tuning (2) and volume
control (1). The CIM converts the press of a button to a bus message that is received by the
EHU, which carries out the instruction.

Antenna, 4D
The system has two antenna systems.

Antenna system 1 consists of one antenna for FM reception and one for AM reception. The FM antenna uses the rear window heating element while the AM antenna is a separate circuit at the top or the rear window. Both antennae are connected to an antenna amplifier located on the right-hand C-pillar. There is an antenna filter mounted on the ground side of the rear window heating element that removes interference when the rear window heating is on.

Antenna, 5D
There are two different types of antenna system for the audio system:

• Antenna system 1 with an AM/FM antenna and an antenna amplifier.
• Antenna system 2 with an AM/FM antenna, FM antenna and an antenna amplifier for each antenna.

The antenna for radio reception are integrated in the rear side windows and are located as follows:

• The AM/FM antenna is located in the rear right side window.
• The FM antenna is located in the rear left side window.

The antenna amplifiers are located below the respective rear side windows and are available in three versions, one for antenna system 1 and two for antenna system 2.

The antenna signal is amplified in the antenna amplifier and fed via a coaxial cable to the head unit (radio). The amplifier is supplied with a trigger voltage from pin 13 (K8B) on the head unit and is grounded through the bolt screwing it to the body.
