AC Outlet - Engine Noise Question

Are you directly hooked into the radio or using the fm transmitter?

 

That is the aux input and is considered a direct connection.

You should not have any noise with this. Might want to see if you can find another unit to test to find whether you have a defective one.

 

Volvo? Hit the menu on the washer stalk, scroll down to "display", hit the menu button again, on the screen that comes up hit the "black panel" option. Does the noise leave?

 

My thought is you will probably need to buy a noise filter from the Shack or some electronic store and splice it into your AC plug feed wires. Or as suggested always a possibility of a defective unit. The Volvo thing I mentioned was because I had noise in my AM radio (yes, some people still prefer it over satellite or FM or CD's lol) and one night during fog I killed the panel lights on the dash for the better visibility and VIOLA....the high pitched whine went away. I've had to use noise filters on several other brands of trucks over the years to eliminate dirty power issues identical to what you're having now..not with sat radio though as I've only had factory radios and antenna's but with other devices.

 

Go to sirius/xm website.Search for "frequency finder".Type in your zip code.It should list about five different frequencies for your area for best reception.Remember as you get out of range of these frequencies you may have to find another bunch.XM makes static reducers but you'll have to pull the radio out.Simple but not portable like the snap.

 

you need a noise filter or run it from the fuse block itself, my bet is the ground your using is from the engine and not the frame
