iPhone Causing Noise

Erik Piazza · October 16, 2015

I just got a new iPhone 6s Plus and when I connect it to my truck via USB cable I hear a high-pitched noise coming through the speakers even when the volume is turned all the way down. The noise is almost like a super high gurgling sound - not a consistent whine. This is on a 2015 Sierra 1500 Denali with the Intellilink system and with iOS v9.0.2. I did not hear this noise with my previous iPhone and I don't hear it when connected only via Bluetooth. Anyone else experience something like this and have a solution?

Make sure you didn't accidentally put ur truck in 4wd. They make a high pitch electrical whine when in 4wd or auto. May or may not help just throwing it out there...
