Can anyone advise please, just bought the above radio last week,can anyone tell me why when the volume is increased to between 8-10(max) a noise comes from the speaker as if it's a motorbike going down the road,or the baffles clattering.

Sound like at this elevated volume the audio amplifier is "motorboating".

As it is a new unit I would contact the supplier as it should not be doing this.

Web search "amplifier motorboating".

Also does it only happen when the USB charging cable and/or any other cables are plugged into the radio?
