First off, this forum is dedicated those interested in the implementation of computers into their vehicle and not for general car or car audio questions. If you would like to learn more, Welcome. Otherwise please refer any future questions NOT about CarPCs to a site that is dedicated to general car audio.
When you checked your fuses, did you use a meter, pull the fuse out completely to inspect it, and did you check the fuses within your engine compartment. The components that you have described that are no longer functioning are all tied to the same circuit so your problem can only be the cause of a blown fuse from a faulty circuit. Now what caused the fuse to blow is a whole different story. The most typical cause is a faulty circuit due to improper installation.
