AUX Ground Loop problem! Can anyone help?

[bagnallman]

Hi

I'm an owner of a 2013 Astra GTC with a slight issue when using the AUX cable for my music.

I have white noise/crackling when plugging into the AUX socket, which I believe is a ground loop isolation problem after some research online. That would mean that there is an earthing/grounding problem somewhere amongst the car's electricals.

Purchasing a ground loop isolator to plug into may be one option - but I was wondering if anyone knew the cause of the issue? Or has had the problem themselves and managed to locate the culprit? 

As finding the issue and cleaning/fixing the earth would be my preferred resolution

All the best

Can I ask what radio system you have fitted?

as the aux is wired different across the range.

Sorry for late reply.

It is a cd400.

For those who may be suffering a similar problem. I have tried cheaper eBay alternatives but they are of poorer quality.

This cable seems to of solved my issue:

However, this is just disguising the problem and any ideas to a permanent fix would be appreciated. Thank you

I'll grab you the wiring info later.
