Hi,

Just had this Pioneer unit installed in my 2003 tahoe with the Scosche GMLAN2SR replacement harness w/chime...at first I thought the buzzing was from the dimmer wheel for the lights inside...it was set at about half intensity. I dimmed the lights all the way down and the buzzing got louder, I turned it up to full and the buzz went away completely...HOWEVER, when I turn the vehicle on, the kind of "whistling" buzz starts up. It gets whinier as you press the gas pedal too... Might this be an issue with the Scosche device or my Pioneer? Thanks for answers!
 
A common problem problem with aftermarket stereos are that they are not "filtered". It sounds like you are getting interference from your alternator. An easy fix. Something else to look at. Check all the grounds to this system. It should have been to your dash and/ or engine block.
