I am not sure if this is a problem or not but I talked to the guy in Pioneer tech support and he said that if no functionlaity is lost then dont worry about it.

Here is my issue: My avic D3 works fine, bypass and everything. However when you are playing a CD or anyhting where it is just like a solid standby black ground,.. the background black area has like "white lines" going through it. It is funny because they are other areas of the image that are supposed to be complately black and are, however the actual back,back, background part has these lines. It is odd. Anyone else have this? Or any input?

Also, I had trouble with the Daytime/Nighttime mode problem also. it i on forever daytime mode. I did NOT hook up the orange wire on the harness for ILL,... does this have to be hooked up in order to use night time mode?

Thats just the default background pic. If you want a different background, go in and change it to a different one. Its in the the navi menu

yea u def need to hook up the ill wire so u get that dimmed mode at night.... there should be one on the wire harness that is the same color... if it is an older model car running a wire from parking light switch would work too.... hope this helps....
