I'm not talking about info screens, i'm talking the visualizations, like funnelweb. These do not go on when i select them when listening to the tuner. Only the "no AF information available" shows.

Yes, I know. This behavior is exactly the same whether you are in player mode or in radio mode. If you are on an info screen, you can't see the visuals when you change them. Because it's on an info screen rather than a visual screen.

So please do exactly what I said and it will work: select a different info screen. Select either Info:Line, Info:Transient, or Info:Off and you will then be able to see your visuals.
