I am using AUX-In connector from my mobile phone (with CTVSKX003 adapter) and noticed that there is VERY loud noise in the speakers if my phone is charging (Brodit charger for Samsung Galaxy S III). That leads me to the conclusion that 12V is quite noisy source of power. Is that a known fact? Is there a standard solution for it? Thanks!

This isnt specific to Skodas. My wifes fiesta (and my old focus) made a really loud humming noise when charging the phone whilst listening to music.,
