If the screen died you might be screwed. it could be the actual screen itself or it could be a problem in the circuit board itself, and there isnt really any way of knowing but i could be wrong on that one.
And honestly your best bet is always to go aftermarket, it sounds much better than stock, and if you invest a little $ and not go for the cheapest unit, it will last longer than the car itself. IMO a double din unit looks awesome in the 05-07 dash.
