Ok folks I need some help! I have the rear entertainment system along with the 6 CD disk changer, VCP and Fold down Screen. I have devloped a hum in the system. It increases in volume under accelaration and makes a "Poping Noise" when the turn signals are used. It only makes the noise when in CD,VCP, or AUX mode. No noise in radio mode. There has been no modifications to this system. It just started (wife drove it) one day. This is driving me crazy. I have posted this same question at quite a few F150 websites w/o any replies. Please if someone can offer assistance it would be GREATLY appericaited.

 

Check your GROUND WIRE, it may have come loose. If it's not loose, I'd redo it make sure its a good, clean contact. Most noise can be traced to a ground problem, it's the first place you should start an then go from there.

 

Thanks! I will try that and see. Nice Ride!
