Hi Hope someone can help. I notice my b8 avant has a dab aerial built into the rear side screen. Would it be possible to connect this to my pure highway dab? I see you can buy a amplifier part number 4F9035225S if I bought this could the output be used for my pure highway. I cannot find and wiring details for the amplifier to prove this. If not could the aerial be used on its own. There seems to be 3 connections on the aerial any idea which ones to use? Thanks hope someone can help Paul.
