Well if the guy i bought my radio from cant find the reciept for the radio i will be having to buy the 30 part for the inside fuse for the rca preouts. With all the interference i am getting from the thing thats what most ppl are saying is my problem. Has anyone installed this piece them selfs? and is there any write ups about it? I searched but didnt see much.

Also when i plug my ipod into the aux plugs in the back and the front port i cant seem to get any signal too the radio. like in the a/v options none of the box come avaiable to use this item why? I did know get the right ipod cable for it..but still would like to know.

thanks, steve

The av inputs have to be turned on before they become availible.

try a ground loop isolator. they are about 15$. i am assuming that you are having an issue with a 4ch amp since you are talking about pre-outs?

yes its a 4channel amp, could you explain more about what that is?

the ground loop isolator would take excess signal noise out of the rca's.

another possible fix...

did you run the rca's on the opposite side of the vehicle from the power wire? if not try that.

no the wires are not by each other...but if theres something wrong on the board, those loops would they fix it like 100%?

im not gonna say that the ground loop isolator will fix it 100% but its worth a shot. another thing to try.. depending on what rca's you have.. there might be a small wire in between the rca's, you can ground one end to your amp and then the other to chassi behind deck.

or another.. is your power wire running anywhere near your alternator? if so... i'd get it as far away from the alternators "radiated noise" as possible by moving the power wire

i think i'm having a similar problem.. i bought a headphone to rca cable for my zune so i could plug it into the inputs at the back of the unit but when i try to use it i get perfect sound quality but stripes of what should be displayed moving quickly up the screen. does this sound like something the ground loop isolaters would fix and if so where do i get them/how do i use them?

Ground loop isolators are a poor solution, and will kill your midrange. Fix the radio instead.

There are no write ups that I know, but just use a meter on ohms, and follow the path on the circuit board until you find the break.

Have you tried grounding your RCAs?

nevermind.. i fixed my problem

hey what did u do to fix it

yeah im still trying to fight to get pioneer to fix mine, if not i will be sodering on the internal fuse.

The ground loop isolators fixed my problem, but I'm hoping to go back & actually find the ground loop itself to eliminate it instead of just cover it up.

Nevermind the problem came back, next I'll try grounding the RCAs to the head unit, and if that doesn't work send the head unit back to Pioneer.

what kind of rca are you useing? Cheap wal-mart/radio shack rcas come with the noises already built into them. If you are go get some better rcas like Rockford or monster cable. 9 time out of 10 when we get a customer talking about whinning noises it is due to the cheap ass rca from wal mart. The ground loop iso is just a band aid not a real fix. It also drops the voltage the amp is seeing from the rca 4v-1 maybe 2v if your lucky. I use to have a installer that would run the ground from the deck to where the ground was for the four channel amp. Might give it a try.

I had this problem with mine, but it was less than a year old so I sent it back to Pioneer and they got it fixed and back to me inside of 10 days. No charge for the work either. Isolators did not work AT ALL for mine, had to use a line out converter and even that sucked. 10x better now that it is fixed. I told them mine was a christmas gift and did not have the receipt and they fixed it anyways.
