Product Installation VideoPurchase AdviceIf your vehicle's onboard system does not come with a protocol box, it is recommended that you purchase a solution that includes one.

Without a protocol box, many vehicle functions may be affected and unable to operate properly after powering on.Applicable Models & Years:For AudiTT MK2 8)(2006-2014)For Audi A3 8P(2003-2012)For A3 8P1 3-door Hatchback(2003-2012)For S3 8P(2006-2012)For RS3 Sportback(2011-2012)For Audi/S4/B7(8E/8H)2005-2008For RS4 2002-2008For Seat Exeo 2008-2012For Audi/A4/B7(8E/8H)2004-2008For Audi/S4/B6(8E/8H)2003-2005For RS4/B7/(8E)2006-2008Product Interface Display and Connection Method16-Pin InterfaceMulti-Vehicle CompatibilityDesigned exclusively for Audi models, this original equipment manufacturer (OEM) power cable and audio converter offers genuine plug-and-play convenience for effortless installation!Key Features:1.
