Active adapter to run a bridge-analog amplifier. mercedes m,gl,r, porsche cayenne, 911

Mercedes/Porsche Active System AdapterActive system adapters retain the function of an amplified factory 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 adapting, 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 assembly.Notes:connector: OEM reinforced MOST system > RCA red/whiteconnector: loose wires vehicles with OEM MOST25 amplifier,Mercedes vehicles with Comand APS NTG2 / NTG 2.5 OEM Sat NavMercedes vehicles without Comand 2.0 / 2.5 OEM Sat NavMercedes vehicles without D2B Optical BusPorsche 986 / 911 / 996 vehicles without YAZAKI optical system yellow: +12V power terminal 30black: GND terminal 31red: +12V switchable ignition terminal 15/Amp remote control/antenna remote controlRCA > output preamplifier retrofit HUfader is not supported OEM units > changer CD / 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 - 04/2012Mercedes A ( C169) 10/2004 - 04/2012Mercedes B (T45) 6/2005 - 06/2011Mercedes C (W203) 02/2004 - 09/2007Mercedes CLK (W209) 04/2005 - 01/2010Mercedes GL (X164) 09/2006 - 05/2009Mercedes GL (X164) 05/2009 - 07/2012Mercedes M (W164) 07/2005 - 04/2008Mercedes M (W164) 10/2008 - 07/2011Mercedes ML (W164) 07/2005 - 04/2008Mercedes ML (W164) 10/2008 - 07/2011Mercedes R (W251) 09/2005 - 05/2007Mercedes R (W251) 05/2007 - 05/2010Porsche 911 (997) 07/2004 - 08/2009Porsche 911 (977) 08/2008 - 05/2013Porsche Boxster (987) 10/2 004 - 01/2009Porsche Cayenne ( 9PA/955) 09/2002 - 12/2006Porsche Cayenne (9PA/955) 02/2007 - 02/2010Porsche Cayman (987C) 11/2005 - 01/2008
