    just got my company truck form central. 2011 prostar. i have a cheap 180 watt inverter i got from walmart a few years ago to run a laptop or something small in my cars. it often messes up my AM reception. have a almost new issue with it now. i have my laptop playing music through the truck stereo, but i am getting a lot of buzz along with the music. unplug the inverter from the 12v socket and buzz goes away. i got what i thought would be a slightly better unit from a pilot yesterday. 300 watt deal with a 12v plug. get the same buzz. i dont need much power. and i would prefer not to spend $400 on some big 2k watt unit to hook up to the battery. at this point i would prefer one i can run through a 12v port in the truck. and not give me the extra buzz with my music.

    so any suggestions on a half decent inverter i can run on a 12v socket that wont give feedback to the radio?

    Try a ground,,from the radio to the frame, preferably a 1/4 braided, that's how I fixed my buzzing noise.

    You have a ground loop. This is very common when trying to play music from a phone/MP3 player through the car stereo while charging.

    This will fix it right up:
    Kensington Noise Reducing Car Audio AUX Cable (Amazon link); $15 or so from various places on line.

    I have 3; that way, if I lose one, I'll still have a spare...

    You don't even have to go thru the hassle of pulling it out to ground it

    exactly

    It's a little box with "RCA" (aka composite) inputs. On the one I have, anyways, the input are 2 males. Output is 2 females. I grounded the box to my bolt in my seat. Pure audio bliss now.

    Google is your friend. Actually, check your local "Car Audio Specialist". That's where I got mine. $20 and a $9 adapter from Radio Shack.
