Mercedes/Porsche Active System AdapterActive system adapters retain the functionality of the factory amplified system.This allows an aftermarket radio to be connected to a system with a factory amplifier while retaining the OEM amplifier and connected speakers by adjusting, matching or converting the signal source output signals to the OEM amplifier input signal.Depending on the vehicle and the installed OEM system with amplifier, various functions such as, sound or subwoofer settings, may be lost.In individual cases, depending on the OEM system and the retrofitted radio, increased noise or turn-on or turn-off noise may occur.Check functionality before final installation.Notes:Connector: OEM Amplified MOST System > RCA Red/White Connector: Flying Wires xa0 Vehicles with OEM MOST25 Amplifier, Mercedes vehicles with Comand APS NTG2 / NTG 2.5 OEM Sat Nav Mercedes vehicles without Comand 2.0 / 2.5 OEM Sat Nav Mercedes vehicles without D2B Optical Bus Porsche 986 / 911 / 996 vehicles without YAZAKI optical system xa0 yellow: +12V power terminal 30 black: GND terminal 31 red: +12V switched ignition terminal 15/Remote control Amp/Remote control RCA antenna > output preamplifier retrofit HU fader not supported xa0 OEM units > CD changer / TV tuner / telephone module must be bypassed in the MOST ring system Fiber optic connector MOST ring: 771000-2100 Fiber optic loop (f) MOST ring: 771000-2001 Make and model: Mercedes A (W169) 10/2004 - 04/2012 Mercedes A (C169) 10/2004 - 04/2012 Mercedes B (T45) 6/2005 - 06/2011 Mercedes C (W203) 02/2004 - 09/2007 Mercedes CLK (W209) 04/2005 - 01/2010 Mercedes GL (X164) 09/2006 - 05/2009 Mercedes GL (X164) 05/2009 - 07/2012 Mercedes M (W164) 07/2005 - 04/2008 Mercedesxa0M (W164) 10/2008 - 07/2011 Mercedes ML (W164) 07/2005 - 04/2008 Mercedes ML (W164) 10/2008 - 07/2011 Mercedes R (W251) 09/2005 - 05/2007 Mercedes R (W251) 05/2007 - 05/2010 Porsche 911 (997) 07/2004 - 08/2009 Porsche 911 (977) 08/2008 - 05/2013 Porsche Boxster (987) 10/2004 - 01/2009 Porsche Cayenne (9PA/955) 09/2002 - 12/2006 Porsche Cayenne (9PA/955) 02/2007 - 02/2010 Porsche Cayman (987C) 11/2005 - 01/2008
