Hi can anyone tell me how to turn off the cd player, or turn the volume down, when the sat nav is on at the same time without turning down the sat nav. a bit confusing? While driving with the sat-nav on and the cd player I could not hear the sat-nav so I turned the little wheel on the steering wheel down but the sat-nav voice disappeared not the cd so I tried turning down the volume controle on the cd player panel but this didn't work either. Owner manual says simply clever apparently I'm not. Can anyone please explain what I'm doing wrong. By the way love my Yeti, his name is Dino. He is a 1.2 SE plus in white. Had him from new in March this year.
