    Why is my stock navi whistling? !

    So pretty much i recently installed the uPAC-GMC2 audio controller so I can use my i-touch to play songs. Anyway Im pretty sure since the installation of the uPAC my radio whistles when I hit the gas and the faster I go the louder it whistles . I can turn down the music and it will no longer whistle but once its turned up again it whistles.. Has anyone else had this problem because of the uPAC controller or is there something else that may cause this that I can fix. Any help is always appreciated. Thanks guys

    Sounds to be a ground problem! Check your ground and try a different spot! Pretty sure that is your problem! Never installed one myself but a whistle is a sure sign of poor ground! Hope this helps!

    A ground loop isolater may help if the better grounding point does not.

    What ground should I check because the uPAC-GMC2 audio controller didn't require or have a ground to hook up. It just pretty much took the spot of the (2) male wires that plug into the navi and had female adapters on the other side of the controller to reconnect the old existing wires that were already plugged in.

    Try to relocate the unit also away from climate control unit and anything else which could cause interference! Tuck away back in dash as far as possible away from other electronics! Move around with truck running and nav unit out to see if it makes a difference! Hope this helps!
