Does anyone have the Pioneer AVIC-N4 installed and working 100%? (bypass or not). If so please reply to this post and let me know.

Reason I asked is because I just received a 3rd replacement unit from Crutchfield. I had it professionally installed 3 times by the same installer (unit is also installed video bypass if that matters in the situation). Before he installed the 3rd replacement new unit in my car (2006 Scion xB), he hooked it up to an external power source that was in his shop and was able to reproduce the same problem as the previous 2 times - Horizontal lines in video. Here's how the problem is reproduced:

1) Press the hard reset button on the front of the unit (this will take everything back to factory settings). The LCD screen will close in and come back out. It will say to insert the appropriate disc.

2) Insert either the west or east DVD

3)Let it do it's thing during the load. It will then either take you to “select your language” screen or straight to the Map screen.

After that go to the CD or Radio screen and then you’ll see the horizontal lines in the background. If you turn the unit off (power still going to the LCD Screen), you will see the whole screen filled with horizontal lines. The installer and I came to a conclusion that the DVD software is causing this to happen. We also tried the 2 dvd’s that came w/ the new unit just to make sure it’s not an issue with the disc - same issue. It doesn't make a difference if we put in the west or east dvd in. As for the temporary work around to make the lines go away. I have to press the hard rest button again and NOT follow the instructions by not inserting the appropriate disc. I’m getting really frustrated at this point. I called Crutchfield, the best they can do is sent out a 4th unit, but before sending it out, someone can test it out and make sure it’s working. I agreed and took them on their last offer. I also asked to get a call when the “test” takes place in real-time so I can make sure this won’t happen again. The rep on the phone said he can make that happen. I’m also frustrated with Pioneer as I called them twice when this first happened, they said that the lines in the background was normal, I didn’t even explain them the situation and right off the bat they told me it’s normal. It sounded like they wanted to get me off the phone quick.

I’m hoping that someone here can give me confirmation if this should be happening or not. Also if anyone wants to see the pics of the issue I’m having, please email me at KryptonKalEl666@aol.com and I’ll be glad to send the pics.
