Static Noise When Listening to the Radio

[caister]

This is really starting to annoy me. I'm starting to think its the Pioneer headunit I've got.

If anybody with good car audio knowledge could help that would be great.

To start off the static noise is not there when listening to MP3's via the USB port.

When I switch to radio I can find pretty much every radio station in the area BUT there is a really annoying background hiss when listening almost like the signal is bad.

So far I have replaced the aerial, the aerial base and the aerial lead all of which made it a little better but its still not perfect.

What should I be checking?

Is it worth running an earth cable to the aerial base instead of relying on the base to chassis connection?

All help appreciated!

have you diagnosed its definately the aerial?d/c it to confirm?just eliminate everything one at a time

I've replaced the full aerial kit with Renault parts so it shouldn't be any of them.

so youve d/c the aerial from the stereo and it still does it?

Is that to see if the static is there without any signal?

yes,as ive said,systematically go through everything,aerial,additional equipment,separate power point,different headunit
