My alpine CDA-9835 HU wont eject my CD's or allow me to use the tilt function... Ive remved checked wires cleaned the face and the connection on the back.... it will ocasionally work, and sometimes itll work randomly and then when the car is off and it goes back on it will not work again. Has anyone experienced anything like this or can anyone offer some thoughts? Im going to E-mail alpine now and see what i can find out.
