I just installed brand new head unit into my truck and system and the FM tuner sounds real bad. When a CD is played it's great but the tuner is bad. It kind of sounds like their isn't a antenna attached. the tuner will be some what ok sitting still in the truck but as soon as you start down the road it statics out so bad you can't listen to it. every thing is hookup correctly like the directions said. Is the sensitvity of the head unit so good that it makes the radio stations sound that bad. kind of at a lose here. any help or insight will help thanks.

i have a 9833 question also. if i hook up the HU directly to the battery what am i supposed to do with the other 12V that is usually attached to other HU's? do i just not attach it to anything?

If you do not want to run the radio off the ignition then tie the red wire to the Yellow wire and take the yellow to the battery or power source. Now you have to remember to shut it off or it will kill your battery and any external amp will still be on too unless you shut off your HU. running your HU this way is not a good idea. Good Luck!

I am headed to the stereo shop tonight to have them look at why the FM tuner sounds the way it does. I know that the radio stations **** here in Pittsburgh, PA but my stock head unit didn't sound this bad.
