nav ratrofit problems

I got all my parts in this week to do the nav retrofit in my 325i 2005. anyway, i'm sitting in the garage now, i got all the parts installed and connected, but the screen doesn't come on when i turn the car on. everything else works. the screen even folds down when i press the arrow button, but it doesn't seem to function any other way. What could i have done wrong? I've checked cables, they seem to be all snug in their places. This is going to drive me crazy. Can anyone recommend anything? is it likely i got a bad screen? I got it from that tim fellow in germany.

Do you have your NAV computer hooked up properly? The display is just a display - something else has to generate the video for it to display. That is either the NAV computer or the TV tuner option.

Can any one post how to remove the climate control (2004 330i) from its location for Nav retrofitting if you dont have the special tool (2 L-shaped metal scales)? Will any flat metal scale do? Does any one have a picture/description of what holds the climate control in its console?
I have NAV in mine, so the climate control was already relocated, but to remove it (before I got the special tool) I just carefully used a dental pick to hook the back of it and pull it out.

Could it be the tint? Is my nav computer messed up? What could be the deal?
Take a look at the 3 diagnostic mode screens on the bottom of this page.Do you have a good number of visible satellites? Is your gyro/wheel sensor operational?
