    Default Major hands free problem

    When I try and use the hands free future it makes a horrible high pitch noise. I can here her talking but that noise is so loud. It does it for Bluetooth and even when trying to use OnStar. Anybody have an idea what could be causing it? The noise comes through the speakers. I'll post a video to YouTube soon and then post it here so everyone can see as well.

    Turn down your speakers it's loud and annoying. I'm on vacation and it just started doing this. Annoying!

    It's a feed-back problem (noise inside the truck is being picked up by the mic, amplified and coming back into the truck from the speakers).

    What could be running, inside the cab, that would product a noise?

    Nothing I can think of, it never did this until recently and nothing has changed inside.

    Did you change phones?

    Could the phone mic be turned on so the feed-back is being picked up there?

    Did you try with the phone bluetooth turned off?

    are you an emt or firefighter with a pager or scanner? radar detector? all might be causing feedback interference

    I did change phones but just updated to the new iPhone but fell in the lake yesterday. :( so now I'm back on my old one and it stopped. Thanks guys for the responses. I'm going to ATT saturday hopefully and purchasing a new phone so hopefully it doesn't start again!

    I have a Aux chord that runs through my tape player, for my iPod, and it makes a similar noise when the radio is turned up when the iPod is playing. The noise mine makes isn't as obvious, but it's noticeable.
