Mercedes Benz AGW Audio Gateway Quadlock 5m Harness Extension

Mercedes AGW Audio Gateway 5m Quadlock Harness Extension Cable Kit DVN-CABE

Description:

The DVN-CABE extension harness and aerial extension cable make it easy to retrofit a universal aftermarket head unit to Mercedes-Benz vehicles fitted with the Audio Gateway (AGW), where the AGW needs to be bypassed, such as when it is water damaged or faulty. The cable runs from the front, where the new radio is going, to the Audio Gateway, which is most commonly in the boot but may be elsewhere. The standard AGW plugs simply plug into the existing wiring, without using a MOST fibre optic interface.

Usually it is best to use a MOST adaptor, but where that is not possible, such as when the factory Audio Gateway is faulty, this cable can be used.

Key Features:

• Bypasses the Audio Gateway: For vehicles where the AGW is faulty or water damaged.
• No MOST Interface Needed: Retrofit a universal aftermarket head unit without a MOST fibre optic interface.
• 5m Cable: Runs from the radio position at the front to the Audio Gateway, most commonly in the boot.
• Aerial Extension Cable Included: A water-blue FAKRA aerial extension cable and an antenna remote trigger wire.
• Factory Subwoofer Connections: Loose white wires for the vehicle's optional factory subwoofers, which may need an additional amplifier.
• Plug-In AGW Connectors: Standard AGW plugs are fitted, so it simply plugs into the existing wiring.

Suggested Compatible Vehicles, others may be possible:

• Mercedes-Benz E-Class (W211) Sedan 03/2002-2009
• Mercedes-Benz E-Class (S211) Wagon 03/2003-2009
• Some Mercedes-Benz SLK (R171) 2004-2011
• Mercedes-Benz CLS Class (C219) sedan 10/2004-07/2010

Check Before Ordering:

• Always check whether there is an OEM MOST sound system installed in the vehicle before placing your order.
• Not compatible with the OEM Mercedes Harman Kardon (MOST) or Bose (D2B) sound systems. D2B systems use different wiring.
• This kit is for vehicles with the Audio Gateway (AGW). Please check that your vehicle has one before ordering.
• Check where your Audio Gateway is fitted. It is most commonly in the boot, but some were fitted locally in other places.
• If your vehicle has a factory subwoofer, it may need an additional amplifier. Please see Factory Subwoofers below, and contact us to check before ordering.
• The CANBUS interface is not included.
• If you are not sure about your vehicle or its sound system, please contact us to confirm before ordering.

Specifications and Connectors:

• Length: 5m approx.
• FAKRA aerial extension cable included, with male and female universal type connectors.
• 14 pin factory speaker connector, including the factory subwoofer connection wires.
• 4 pin (3 used) power connector.
• CANBUS connector (for the front connection, CANBUS interface not included).
• Antenna remote trigger wire.
• Standard AGW plugs fitted, simply plug into the existing wiring to bypass the Audio Gateway (AGW).
• The extension cable has standard Benz Quadlock plugs, so you may need to use an adaptor or hardwire to the new radio.

Installation - Cable Routing:

• Route the cable harness along the side of the vehicle to the front, and lead it up at right angles to the centre console in front of the front seat.
• Keep the cable away from power wiring, and avoid sharp bends or pinching the cable under trim or seat rails.

Installation - Connections at the Audio Gateway (Most Commonly in the Boot):

• Unplug the 14 pin speaker connector, the 4 pin power connector and the antenna connector from the electronic unit (the amplifier, among others), and connect them to the matching connectors of the cable set.
• Connect the antenna line (the water-blue FAKRA antenna connector).
• If your Audio Gateway is not in the boot, check that the 5m cable reaches before you start.
• Test the system before refitting the trim, including all the speakers, the aerial and the subwoofer, if fitted.

Factory Subwoofers (If Fitted):

Some vehicles have a basic factory subwoofer, for example a single subwoofer on the rear parcel shelf, and others have a larger system with a separate amplifier. The loose white cables are the connections for the factory subwoofers, as follows:

• Pin 1: Subwoofer 1 plus
• Pin 2: Subwoofer 1 minus
• Pin 3: Subwoofer 2 plus
• Pin 4: Subwoofer 2 minus

With the Audio Gateway bypassed, a factory subwoofer may need an additional amplifier. Larger factory subwoofer systems need a separate amplifier, and you may want to run RCA cables from the radio at the same time. Factory systems vary, so please contact us with your vehicle details before connecting the factory subwoofers.

SLK Vehicles - CAN Bus Distributor:

• Remove the side panel in the driver's footwell (2 x T20/T25 Torx screws, one in the middle under a plastic cap and one at the top of the edge). The panel is snagged on other parts, so pull it out and down.
• Pull the carpet upwards and open the cover of the black plastic channel underneath by unhooking its plastic hooks.
• The CAN bus distributors are located in the channel. Pull the marked distributor upwards out of its socket.

Please Note:

• Professional installation is recommended. The wiring is vehicle specific, and incorrect connections can damage the radio or the vehicle electronics.
• The manufacturer's instructions are written for left-hand drive vehicles. In right-hand drive vehicles, some positions may be mirrored.
• CANBUS interface not included.
