How to confirm if a car has MOST25
Look behind the head unit or at the back of the CD/DVD changer — you’ll see an orange plastic fiber optic cable with a dual plug.
Check if the car’s audio system menu shows Logic 7 surround — often a sign of MOST25.
Match the infotainment generation (NTG2/2.5/early NTG4) with the model year.

In-car Audio Retrofit:
The Core Role of the Sound Source
In the field of in-car audio upgrades, the quality of the sound source is the most critical foundation for achieving high-fidelity performance. Due to the varying trim levels—high, medium, and low—of luxury vehicles, some factory-installed head units in mid- to low-tier configurations fail to meet the stringent requirements of audiophiles. These systems often output high-level audio signals that have already undergone factory tuning and internal amplification, resulting in compromised sound quality.
The audio interface box addresses this issue by isolating the audio data commands from the factory head unit—such as volume control, EQ settings, and other sound effects—and bypassing the built-in OEM amplifier. It converts vehicle-specific network audio signals into standardized optical or coaxial digital outputs that are compatible with professional-grade audio equipment.
By doing so, it restores access to a clean, unprocessed sound source and enables integration with high-performance aftermarket amplifiers equipped with digital DSP functionality. This seamless conversion ensures that audiophiles can enjoy a truly refined listening experience, with significantly enhanced soundstage, clarity, and depth—ultimately achieving a professional-level audio upgrade in their vehicle.
