Okay, so I finally finished the aesthetical install of my Pioneer AVH-P4000 DVD in my 08 Mazda 3. At first, all I had was the headunit installed without the stock lcd screen that displays temp, time, etc. Well I went back and got everything fit and looking nice. Now whenever I turn on the car (its not EVERY tme but most of the time) I get this strange electrical noise. It kind of a whir or a whine and it lasts for about 5-10 seconds..
any help greatly appreciated
I already pulled it out once and made sure there was no bare metal touching either the wires or anything else
