Hey there Bob. Found your post and it wasn't in the best place to get you the help you need, so I moved it for you to the section that applies to your year/model truck. That way those who can help will see it, here's a link: http://www.ramforumz.com/showthread.php?t=142406.
Hello, I just posted a question but maybe I put it in the wrong section, anyways I'm having radio problems in my 2004, 1500, QC with Infinity system, navigational radio where the volume will go from normal to really load and the knob control sometimes won't work unless you jiggle the knob( maybe dirt) but the steering controls work to turn it down. Could there be a amplifier or something going bad? Thanks in advance, and glad to be here around a bunch of good people. Bob
