Didn't get to mess with the radio today. I am starting to think it is the HU also. I will try hooking it up the way I had it hooked up previously and see if the noise goes away. I may pull up the center console and seperate the RCA and speakers from the Power cable as they are running side by side, but in seperate wire looms. If that doesn't help then it must be the radio. Problem is I purchased it on ebay online! UGH! saved about $30 bucks, no I wish I had just gone to best buy! Will post tomorrow afternoon and let you know what happened. Thanks for all the input though, I appreciate everyones help! Shame too, once it is off of 01 and swithing between settings and stations it sounds GREAT!
