Did you match up the wires in the back appropriately with the factory wiring? Did you hook up both power wires?

[joshtazz 1]

yes all the wiring is hooked up right i tripled checked and what do you mean a second power wire?

Head units have two power wires. One is constant, the other i switched with your ignition and only sees power when the ignition is turned on. On most head units they are yellow and red.

some of the decks have a emergency wire hook up . so when u are driving the screen will go off on less u park the car and put the e-brake on, make sure this wire is hooked up properly .

That or you have a faulty deck from the sounds of it.
