    Hi

    My iPhone 3GS use to connect to my car stereo using 'Aux In' 3.5mm jack connection with no trouble.

    Now using my 4S I get terrible feedback, a crackling/hissing noise I can hear in the back ground. I have checked all the settings and all is the same as on 3GS.

    Te strange thing is the noise is only there when music is open. As soon as I close music, ie to look at settings the noise stops.

    Any suggestions you wonderfully clever people! ;-)

    Thanks

    Daniel

    Have you tried a different AUX cable?

    Have you got a case on the phone? I had the same problem until I took off my case.
    Also when playing a song don't put the volume on your phone on full, instead put it at about 3/4 then use the car stereo volume to adjust to the sound you want.
    Hope this helps!

    Still doing it.

    The strange thing is, as I turn down the volume, the feedback gets louder. Not more noticeable, actually gets louder?!?

    No. I thought about interference from charger but alas not! Have tried my wife's 3GS again and it's perfect. Real puzzler!

    It is the phone then. My only thought is that the output of the 4s uses a different frequency than the 3GS which doesn't or wouldn't surprise me. Solution would be getting an output cable that is made for iPod control. That plugs into the bottom of the phone. This takes the music digitally as the headphone jack does not. Hopefully your stereo allows for this of not it is a hundred dollar fix at any stereo installation place.
