Well it very well could be a failed transistor in the stock radio. It could also be something in the antenna system. I would try replacing the stock radio for starters. If the noise varies with engine rpm I would say there is something wrong in your wiring. Could be a loose ground, some wire shielding that has gone bad but these are some worse case scenarios, my guess is a transistor or capacitor has gone bad in the stock headunit. Keep us posted.

This can also be caused by your alternator it is with engine speed, the cause being a bad diode.

yea this could be a cause does the buzzing increase as you give it some gas?

Yea it gets louder when i speed up. I also have any fm transmitter for my ipod and when i listen to that, it makes a constant and louder buzzing sound. I am planning on getting a new radio anyway, so i don't want to spend money on a radio and it still make that sound.

Sound to me like it is your alternator. I would try that before spending the money on a new radio, just to have it plagued with the buzzing noise.

I got the radio installed today at Circuit City today and the buzzing went away. I was really nervous when I got there and bought it because they would of put it in (I got free instal because they have a deal there) and they would call me over to my truck and say: Sir, there is a really loud buzzing sound coming from the new radio. But they didn't. The radio is a Sony Xplod CDX-GT420IP. It has alot of stuff like AUX front input, iPod connector, and wireless remote. It is extremely nice. Here is a link to it on Sony's site: Radio

Congrats, I am glad the noise has cone away. Like I thought, it must have been a worn out component in the stock radio (transistor, capacitor, diode, etc.). Once something like that goes out it is very had to find and even harder to fix (since surface mount components are so small and hard to solder).

Well that isn't all of this hole fiasco. Sounds a little strang but: On the way home from Curcuit City (Sunday) the radio was fine, but later I had to run an errand and the radio still makes the buzzing sound. So on Monday I went back to Curcuit City after school and told them it makes that sound and they looked at it and said the antenne was a little loose. So they tightened it and I got in the truck and the radio was fine for about a minute, then it made the buzzing sound again. So I really don't know exactly what is causing the sound execpt that it isn't the radio itself. Also one thing I forgot to mention in the first post is that it only buzzes when the engine is running. Not sure if that helps or not, but it is worth telling you guys.

you need a noise surpressor. It connects inline on the posotive or ground (I'm not sure). I need one in my truck as well, it is caused by altenator whine. This doesn't mean that the altenator is bad. Make sure that you get a good quality supressor.

Yeah that should probably do the trick. Sounds like you are just getting noise in the power wires (especially since it only happens when the truck is running).
