Hi. I have a 2015 A6 Avanti and had the same issue with the No Satellites. Reading various posts, most recommended a new shark fin (aerial) but this was gonna be a big job chasing the GPS cable around the car. My solution was to ping out your A/C unit. I used 2x plastic bike tyre levers, then unscrew the holding bolt on your media centre which is above the A/C unit. There are 2 x plugs either side of this unit that must be unplugged to allow access to the rear. Unplug the old one GPS (blue) then plug the new GPS Ariel in & drop it at the back of the A/C unit as there is room for it. The media & A/C units can then be put back. Hey Presto 9 satellites registered & all for 30 mins work & a £7.99 Active GPS Antenna from Amazon.
