Hope someone might be able to help.

Have had a Bury 9060 music fitted to car (connected to CD30 Full Canbus), all is fine apart from when I connect my Iphone to the dock connector and turn the volume up, there is a destinct almost interference noise in the background. It sounds like beeping noises (sounds silly, like morse code beeps) aswell as buzzing noises and if i navigate across the screen on my iphone the buzzing noise reflects what i am doing on the screen.

Does not make the noise when streaming via bluetooth.

Its really hard to describe the noise, have had the professional installer back out and he is not sure, still awaiting a call back from Bury Technical. Hoping someone can suggest what it is?

Was bought primarily for the music side, handsfree aspect no problems at all.
