so i have a 97 eldorado basically i want to know how to figure out what deck will fit in my car. i want a touch screen with a gps sytem and a dvd player. where can i get the demensions?

 

you need to find a double din install kit for it. almost any aftermarket touch screen GPS/DVD is double din and will fit in it. good luck wiring it to all the speakers since you're going to have to run new wires to them if you don't have bose. if you have bose you're going to have to run new wires AND get new speakers. and you're going to have to connect your new stereo's constant and switched to the car's constant 12 volt so that the stereo has memory, but make sure you turn it off when the car is off so it doesn't drain the battery.
