iphone/car stereo - audio interference from engine

Darren, what make of radio do you have?

As said the simplist way is to buy a suppressor for the live input on the back of the radio.

Engine nose is caused by interference from the live(s) of the car radio being near the signal feeds of the speakers/inputs etc. So, if its and aftermarket radio, it should, being an 02 car, used the DIN plugs from the car to plug straight into the back of the head unit. If this is the case, then the actual fault is going to be with the headunit itself as most cars, and that includes golfs, are very well suppressed in the begining.

It can also be the signal cable you are using to connect your ipod/phone to the head unit. If its a really cheap and nasty one, then this can also pick up noise etc from the car.

To be honest, i hevn't heard this problem in a long long while thats for sure.

So check the wiring at the back of the radio to make sure all is well. Make sure that you are getting a good earth at the radio (Measure the volatge between earth and live at the radio, and also at the battery, they should be the same or only very very slightly out). Try a supprssor and/or a better quality shielded lead. If all else fails look at something like the Harmon/Kardon Drive and play, or a FM modulator, or check to see if your radio has an Aux in at the back of the unit using Phono plugs, if so, buy a phono-3.5mm lack lead and try that.

It's this one http://www.amazon.co.uk/CA-5555i-MP3.../dp/B000EBCDZ0

It has the standard car radio plugs in the back. It has phono input leads, which I have plugged a "phono to 3.5mm jack" lead in to. This is a new lead. I got interference from the old lead as well. I've read about people still getting interference using FM transmitters.

I'll check I'm getting a good earth
