Hello, I tried to work with the search here on the board, but only find fragments on my question – if the search works at all. Therefore: At a price of EUR. 3500.- for the Navi+ on the A3 I think, whether it is not useful to completely do without the multimedia and to have the devices installed later on. My question: If I order an A3 (TDI) completely without a radio, what hurdles do I have to take? Are box grids in there? Are there already cables in there for boxes, or do I have to pull everything? Do I have problems already programmed by the CAN bus later and possibly even higher costs for „Diez-Adapter? I have a reasonable MP3/CD radio (analog) with reasonable performance. (I used to have a DAB52, which was ok, apart from the DAB times). Active boxes and boom boom boombass do not have to be. As a Navi I would be sufficient a 1-DIN sound system or a system with an extended monitor (1 DIN).
