About this product
If your Audi A6 or Q7 from the 2009-2015 era still has the factory MMI 3G system, this decoder box is the way to add wireless CarPlay and Android Auto without swapping the whole head unit — the original screen and steering-wheel controls stay in place, so you keep the factory look while getting modern phone mirroring and navigation. The listing covers both the 6.5-inch and 7-inch variants, and that is exactly the first thing you must confirm: measure your existing display or check your MMI version before ordering, because the two screen sizes use different harnesses. Second, check your model year and MMI generation — this kit is listed for MMI 3G, not for the later MMI 3G+ or MIB units. Third, plan for installation: the box goes behind the dashboard and needs to be connected to the factory wiring, so either budget for a professional installer or be comfortable removing trim panels yourself.
