Skoda Octavia sat navv

hi all

i have just put a genuine skoda sat nav in my octavia , all works well but when i switch to multichanger in boot i get interference through the speakes, has any one got any ideas, doesnt do it on radio nor the sat nav

had something like this on radio many years ago turned out to be wiring too close to aeriel had to shield adjacent wiring with tin foil , cover this with insultion hope this helps
