Overview
The audio unit acts as the processor for all audio functions. Select audio functions from the audio unit buttons or the audio remote switch (on the steering wheel). The center display provides the current audio status.
The audio unit has a built-in EEPROM (electrically erasable programmable read-only memory). This memory holds the audio presets (AM/FM radio frequency, sound settings, etc.) even when the battery is disconnected.
A security signal is daisy-chained between the audio and vehicle components for integration into the vehicle's security system.
There are two audio systems available for the TL
- The ELS audio system is available on vehicles with navigation. It includes surround sound with 10 speakers.
- The premium audio system is on vehicles without navigation. It includes 8 speakers.
