well took my car in to the dealer when i got it back the nav screen was just showing blk and white line then it started working fine after a few min. when i turned off the car and started the car it did the same thing but the screen just showed a few colors and I have a nav conversion with rgb1 could it be the wires to my relay converti. when i switch to my dvd its the same thing with dif colors. I was about to just hook up direct and disconect the rgb1 just havent had a chance to do that, or is my screen screwed. im thinking its the connections just need some imput. If i can fix it my self i would rather do that.

J mack if your looking could use your help .
