witam, chciałem wymienić oryginalne radio audi concert 1din które ma wzmacniacz po prawej stronie bagażnika na coś w tym stylu jak na zdjęciu, i dowiedzieć się od razu co jest potrzebne aby takie radio wymienić zanim kupię na ślepo

Take 1 Din from Pioneer, they have the same lighting as the rest of the OEM lighting in the B6 interior, lots of options like adjusting the tone of each speaker separately, lighting, BT applications, etc., I have an older DEH S5000BT, for a long time, it was a bit more expensive than the other 1 din but 100x more options, I'm sure there is a newer one with a newer application.

To connect you need wires that just plug in so that your rear speakers and amplifier can work and an extension for the antenna if you have 9+ bass speakers like the vast majority of b6s.
