Hi Folks, I've got a problem when trying to use my Aux port (ooh eer), with or without plugging into the connector, the HU emits a buzzing noise regardless of which of the 3 settings I choose. I am able to play music via the port but it has this underlying buzzing noise. Can anyone please advise ?

Sorry I meant I get a buzzing sound through the speakers, not from the HU, D'oh !

Anyone have any idea's ?

make sure your aux cable is pushed all the way in where it plugs into the car, ive found it can be a very tight fit (ooer). failing that try another aux cable

Thanks for your reply, much appreciated. Unfortunately there is a buzzing noise whether the cable is plugged in or not

i had this with mine, the buzzing noise is a constant unless the aux cable is plugged in to both the car and the device you are connecting to. If the cable is plugged in both ends and you still have the buzzing you likely have a bad cable. I bought one of these cables a couple of years ago and not had any problems since, expensive i know but well worth it. http://www.amazon.co.uk/FPUK-Metre-3-5mm-Stereo-Electronics/dp/B001D8I668/ref=sr_1_10?ie=UTF8&qid=1400504292&sr=8-10&keywords=aux+cable

Thanks Bian, I'll try a better quality lead and see how it goes
