Hi there -

I recently purchased an 03' 330 ZHP from dealer - i noticed while listening to the radio that the sound goes flat in and out randomly. I tried turning off the 'expanded' sound button but it still seems to do it - i've directed sound to each of the speakers and they sound fine - so i'm a bit lost - it's hard to explain - just the sound seems to go flat -

i know this is kinda random - but anyone have any experience with this?????
