Welcome to the 'Fest. Find your way to the WIKI and read up on the section that describes the system in your car. It's probably not what you think it is and upgrading it requires this knowledge.

I kept my factory nav and replaced the amp and speakers and added a sub. Others have done a double-din wide-screen head unit and kept the factory amp and speakers.
