I have a MDX 2004 which is having issues with the screen. I have been told I needed a new Alpine dvd unit. (the unit under the seat) which will run us 1K +, so needless to say that NOT going to happen. we cant regulate the air/heat so its something we need to have fix (we live in Texas and its hot). sometimes the screen will work and come on but then it will just reboot as if I'm turning on the car again. Any help here is welcome. Thanks!
