The use of audio systems in later models is a digital hub for information such as navigation and the location of fuel stations. Many new terms roam about the presence of all these acronyms and abbreviations; these include the ACM (Audio Control Module), FDIM (Front Display Interface Module), FCIM (Front Control Interface Module), GPSM (Global Positioning System Module), and APIM (Audio Protocol Interface Module). The signals are received from the radio by multiple modules, which are then processed through the APIM to the FCDIM and to the speakers via the ACM. The U codes stored can be helpful to technicians in diagnosis but should not be considered as solutions. For theft protection, the radio receiver in a model from 2007 and earlier is anchored with clips that need a special removal tool. Dismantle the
Antenna and electrical connectors and then reverse the process to install it. Starting from model year 2008, when the ACM or FCIM is replaced, the original configuration data must be downloaded and uploaded to the new unit. In order to reach the FDIM and APIM, remove the center trim panel and several fasteners. The electrical connections must also be disconnected. Calibration of the touchscreen must be performed any time the FDIM and APIM are disconnected, which involves several steps. Different locations require different speaker removal processes. This includes the front and rear door speaker, subwoofer, dash speaker, and also A pillar speakers. The installation involves the reverse of the removal.
