HI I have a Alpine IVA-D300 for sale it comes with the headunit with monitor along with all cords and the brain it also comes with an additional monitor that has a slight problem with its motor as far as the screen coming out it still works perfectly it just needs help as far as coming out and going in i was quoted a price of 80 dollars by Gibson to fix. So you will have a spair just incase you break the headunit or someone breakes in you car and steal you head unit and can't get your brain just plug in the other one and your good to go. Both are in excellent condition. I would like to get 800 dollars obo for the entire setup just hit me up.
