Circuit-/System description

Extra sound input
The 3.5 mm (1/8 in.) AUX input is located in the bracket. The AUX input circuits can be connected directly to the radio or to the multimedia player interface-module (if present). When a portable playback device is connected to the AUX input, an internal switch opens the detection signal circuit and the radio switches to AUX as sound source.
When not equipped with a multimedia player module all circuits from the extra connection are connected directly to the radio. When a device is connected to the AUX socket an internal switch opens. Radio detects the device and switches to AUX as sound source. Acoustic signals from the device are sent to the radio from the extra input via left, right, and normal sound signal circuit.
If the car is equipped with a multimedia player module all circuits from the extra connection are connected directly to the multimedia player module. When a device is connected to the AUX jack the internal switch must open. The multimedia player module identifies the device and sends a serial data request to the radio to swap to AUX as an audio source. Acoustic signals from the device are sent to the multimedia player module from the extra input via left, right, and normal sound signal circuit. Multimedia player module sends these signals to the radio.
USB port
The vehicle may be equipped with a USB port in the bracket. This port allows USB connection to the infotainment system from the portable media player or a USB storage device (Memory Stick / flash device). When a device is connected to the USB port, the system identifies the device and switches to USB as sound source. When a USB device is connected it can be controlled from the radio controls.
The USB port is connected to the radio or multimedia player module (if fitted) via a normal USB cable. Mini type USB connections are used to connect the cable to the USB port and to the radio or multimedia player module. Standard USB male to female connections are usually used to connect the USB cables together where an inline connection is required. There is usually an inline cable between the console and the I / P wiring.
Not all portable devices are compatible. Memory Stick / flash devices are restricted to MP3 and WMA file types. Video transfer is not supported. Read the owner's manual for information about using USB devices.
Multimedia Player interface module (option)
All non-DVD capable infotainment systems are equipped with a multimedia player interface module. The multimedia player module is a device that can receive input from analogue or digital sound playback. The inputs can be received via AUX input, the USB port or wirelessly via Bluetooth ®. Multimedia player module and radio communicate via serial data. The message is used for the radio to control the input source, and for the multimedia player module to send discovered information to the radio when other devices are connected. The multimedia player module is used to allow these inputs in systems where the radio does not provide integrated support.
The multimedia player module receives input from another device and transfers the acoustic signals to the radio for playback. All input from the multimedia player module is transferred to the radio as analogue acoustic signals via left, right, and normal acoustic circuit.
Extra sound input
|
•
|
When a device is connected to the 3.5 mm (1/8 inch) input, the infotainment system switches automatically to the device. If an extra device has already been connected, press the AUX or CD / AUX button to select the device.
|
|
•
|
If the system detects the device, but sound is not heard or not clear, try connecting the device with another cable, cables can degrade over time or become damaged.
|
|
•
|
Playback from an audio device that is connected to the 3.5 mm input can only be controlled using the controls on the device.
|
|
•
|
The volume control on the device may need adjustment to ensure sufficient playback volume through the infotainment system.
|
USB
|
•
|
When a device is first connected to the USB port the infotainment system automatically switches to that device. If an extra device has already been connected, press the AUX or CD / AUX button to select the device.
|
|
•
|
Low battery voltage in a portable media player can prevent the device from connecting to the system, or can cause communication problems. Check the device battery status and replace or charge if necessary.
|
|
•
|
If possible connect the device directly to the USB port. Only use a cable if it is required to connect the device. Use of extension cables can cause communication problems.
|
|
•
|
If a cable is required for connection, try to connect the device using another cable, cables can degrade over time or become damaged.
|
|
•
|
Try to play back sound from several USB devices when diagnosing USB problems. Compatibility can vary depending on the vehicle's equipment. If the infotainment system can control all types of USB device, the cause of the problem is not the vehicle's system. Non-functioning device (s) can be incompatible or contain an unknown media type.
|
|
•
|
If a ‘Device Not Supported" or similar error message is displayed, it indicates that the system has been connected to the device, but cannot communicate with it correctly. This does not mean a problem with the vehicle system. The device may be incompatible, require a "reset", or may require a software / firmware update.
|
|
•
|
If a ‘No Supported Data Found" or similar error message is displayed, it indicates that the system has been connected to the device and communicates, but cannot find any compatible files/data. This does not mean a problem with the vehicle system. Check that the device contains compatible media/file types.
|
|
•
|
Bad connections or damaged USB cables can cause intermittent or no operation of USB devices. Inspect contacts, terminals and cables for damage and replace components as necessary. Ensure that all USB inline connections and connections to components are secure and that connector holders/ locks are secured.
