Hey Everyone - I have a 2005 4.4i w/ 77k. I have the stock, factory naviagation. The screen is doing something really weird. At times, (except for the dead pixels), I have a vibrant color screen. Then, randomly - doesn't matter temp hot or cold or any other factors, the screen is s dull gray but you can still see the details of the map. Then, the screen turns hulk green, completely green!

What's going on? Is this main unit going bad or is it just the screen? If its the main unit, is dynavin still the way to go or are there any other products available?

Thanks to all who answer!
