Decided to put this retrofit on hold as the reason VW (and Audi) stopped offering TV Tuners in EU vehicles since 2016 is because DVB-T broadcasts are going offline in favor of DVB-T2 somewhere between now and 2020. The 2018 Audi A8 is the first to feature a new DVB-T2 tuner, but i'd rather wait until they release a VW with one of those.
