Hi all, I have a 2005 A3 Sportback. I removed the original Concert radio, converted the console to 2DIN and installed an Android auto screen. Everything is working ok, Steering wheel controls and all. But, I have two problems. Rear speakers/sub were not working (I fixed that partly) and radio receiption is bad. Its like the oem aerial is not powering up or something. I tried connecting the brown fakra connector to a converter it had included in the package but no joy. Used an amplified one, still reception was bad. I am 99% sure the amplified aerial is not powering up. Any advice?
