Pull off the cable that is connected at the negative terminal of the battery. Pull back the Instrument panel center bezel. Take out the radio mounting screws and thus releases the radio from the instrument panel, just pull it out merely to allow access to the electrical connectors, and the 
Antenna Cable lies at the back of the radio unit. The electrical connectors and the antenna lead must be disconnected from the backside of the radio and the radio taken out. Installation is the process opposite to the removal and is similarly carried out to assemble a device on a surface it is to operate on. For front door speakers, first, you have to take out the front door trim panel and next, you have to remove the mounting screws of the speaker. To accomplish it, reach for the pin, disconnect the electrical connector from the speaker, and then take the speaker out. Removal and Installation refers to responding accordingly; it means that installation is the antonym of removal. The front door speaker trim panel and the speaker mounting screws must be detached for this part. To remove the speaker, pull out on the speaker, then unlock the electrical connector by pressing on the tab located at the top of the connector and take off the speaker. Removal on the other hand is the reverse of installation. For rear door speakers, pull the rear door trim panel, then there will be screws that will have to be removed for the speakers. Slide out the speaker, unscrew the electrical connection and take out the speaker. Removal is the exact opposite of installation. For the instrument panel speaker, on 2009 and later models, pull the mat at the upper storage compartment outwards, then two screws will be revealed, by raising the upper storage compartment slightly, those two screws are detached so as to release the electrical connector of the speaker. Detach the top most portion of the storage area and in some instances, you shall have to unscrew the speaker mounting locations before lifting the speaker. Installation is the process of putting back something that has been earlier removed.
