June 30, 201015 yr Did you match up the wires in the back appropriately with the factory wiring? Did you hook up both power wires?
July 1, 201015 yr Author yes all the wiring is hooked up right i tripled checked and what do you mean a second power wire?
July 1, 201015 yr 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.

July 1, 201015 yr 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 .
