Ok guys I have been looking for a solution everywhere and this is the only place i can do it

I have just got my head unit back them saying that the replaced the harddrive and i went and installed it today

same thing happens

1. music playing from cd drive is distorted bad it did this also on the music I had on the harddrive it did the same thing

2. (how it started) When I hooked up the microphone that came with it it all the sudden caused this problem

is there any way or thing anyone can think of to help me out thanks again

I have also done a reset on it and still does the same thing :\ im sooo lost

Plugging in the microphone would not cuase this problem. Just to confirm, but your mic is plugged into the mic port and not the "Guide SP Out" port?

If you sent it to Pioneer for repair and it came back with the same problem, I would send it back to them... All repairs include a 90 day warrenty.
