To expel the connection between the radio and the car, remove the cable from the negative terminal of the battery. Subsequently, it is required to remove the center trim before unbolting the radio mounting screws with differing patterns between the early models and the subsequent ones. Remove the radio and unscrew the wiring and electrical connectors such as the antenna lead and the wiring harnesses. Concerning the speaker access, unscrew the bolts at the back of the mirror to get hold of the wiring and pull out the speaker out of the mirror. To get to the main door speaker, first, eliminate the door trim panel, pull the electrical connector off, and then unscrew the mounting of the speaker before taking it out. For models from 2010 and later, pop the center speaker grille and you will find mounting screws and after removing them take out the center speaker located at the dashboard. Installation for both the radio and speakers is the reverse of removal They simply unscrew the four screws on it and put it back into the car.
