I hope its not just me, but when navigation is on and the bod is talking re the route how the **** do you turn him off if you do not need it to play navigation anymore,I have gone into other things on the satnav and he still talks over everything, radio, media, or car information the only way to stop it is to take the thing off of the cradle and switch off on the top button and its driving me madCAN ANYBODY HELP PLEASE
