When I use turn signals hear a high pitch whine, Also hear the same when using radio or backup assist.
Will occasionally hear a pop when turning radio on then goes to the whine noise. Any suggestions?
Thank You

    Does this whine go up and down in frequency when you push the accelerator pedal?

    It sure does. Any suggestions? I am dumbfounded.
    Thanks.

    I would suspect interference from the alternator. This may require some
    shielding. Car audio shops are very familiar with this type of problem and
    solution. best Joe aka Shiftright
