Everything is included. If the existing antenna is already designed for DAB, it can probably be used, otherwise there is no DAB reception, which would then be pretty pointless. The laying of the antenna cable, like the power supply, can be relatively complex (see also my review under the product). I also had to buy a new cover for my Skoda (2010). Radio and reception are great - but I would buy a Pioneer model today, where you can set station favourites on buttons.
