bdegrand Posted April 4, 2018 Share Posted April 4, 2018 I noticed there are 2 separate circular vent holes in the headliner above the driver and front passenger seats. Very small circles (nickel size) with tiny dot like holes. What is the function! Quote Link to comment Share on other sites More sharing options...

You will have to use the turn knob just below the screen. May have to turn it up over half to drown out all the noise. Unfortunately that type of noise gets louder as the noise canceling radio gets louder. Sometimes the pitch goes up too. 2 Quote Link to comment Share on other sites More sharing options...

If Ford would invent a mute button for the passenger they’d sell millions of them. 2 Quote Link to comment Share on other sites More sharing options...

Assimilator Posted April 4, 2018 Share Posted April 4, 2018 (edited) You'll also notice at least one in the back seat toward the center, at least in most CD4 vehicles. Edited April 4, 2018 by Assimilator 1 Quote Link to comment Share on other sites More sharing options...
