Frequently Asked Questions about ASA Mercedes Audio Gateway MOST>RCA

How is the ASA Mercedes Audiogateway MOST>Cinch installed?

For the installation of the ASA Mercedes Audiogateway MOST>Cinch, you first need the correct connections between your aftermarket radio and the OEM amplifier. Use the red and white RCA connections. The yellow wire is intended for +12V constant power (terminal 30) and the black for ground (terminal 31). It is important to check the functionality of the MOST ring connections before final assembly. If your vehicle has a defective OEM module such as a CD changer, remove it from the MOST ring to avoid interference.

Which vehicles are compatible with the ASA Mercedes Audiogateway MOST>Cinch?

The ASA Mercedes Audiogateway MOST>Cinch is suitable for various Mercedes models such as the CL-Class (C215) from 02/2004 - 08/2006, E-Class (S211/W211) from 03/2002 - 02/2008, S-Class (W220) from 02/2004 - 09/2005, CLS (C219) from 10/2004 - 06/2008, and SLK-Class (R171) from 03/2004 - 03/2008. It is important that these models have a COMAND navigation system. Vehicles without COMAND OEM navigation or without a D2B optical bus system are not compatible. Pay attention to the specific model restrictions when selecting, as compatibility is crucial for functionality.

What functions does the ASA Mercedes Audiogateway MOST>Cinch not support?

The ASA Mercedes Audiogateway MOST>Cinch does not support a fader function. This means you cannot adjust the volume separately between the rear and front speakers. Sound and subwoofer settings may also not be available depending on the vehicle-specific OEM active system. This results from the signal adaptation from MOST to RCA, which only ensures basic audio transmission but cannot retain all customized OEM functions. You should consider these limitations if you want to ensure a balanced sound profile for your vehicle.

What connections does the ASA Mercedes Audiogateway MOST>Cinch have?

The ASA Mercedes Audiogateway MOST>Cinch provides specific electrical and optical connections. Electrically, it is powered by +12V constant current (terminal 30) and ground (terminal 31). The audio signals are transmitted through the RCA connectors in red and white. For the optical connection within the MOST ring, a fiber optic connector must be used, such as item 771000-2100 for the fiber optic loop (f). These optical connections are essential for maintaining communication between the system components of your vehicle.

What must be considered when integrating into the MOST ring?

When integrating the ASA Mercedes Audiogateway MOST>Cinch into the MOST ring, it is important that all fiber optic cables are correctly connected. Use item 771000-2100 to close open connections. If a component of the system, such as a CD changer or TV tuner, is defective, it must be removed to avoid disrupting the signal flow. These steps ensure uninterrupted communication within the vehicle system. All connections should be checked for functionality before final assembly to avoid later errors.

How does the ASA Mercedes Audiogateway MOST>Cinch affect the existing sound system?

The ASA Mercedes Audiogateway MOST>Cinch allows an aftermarket radio to be connected to existing OEM sound systems by adapting the output signals of the aftermarket radio. The original amplifier and speakers remain active, ensuring the preservation of existing sound quality. However, there may be limitations for vehicles with an existing OEM active system, particularly regarding the fader function or special sound adjustments. It is important to consider all limitations during installation to guarantee the best possible integration.

What role does the fiber optic cable play in the ASA Mercedes Audiogateway MOST>Cinch?

The fiber optic cable in the ASA Mercedes Audiogateway MOST>Cinch is essential for optical signal transmission in the MOST bus system. It ensures that all control units in the vehicle can communicate efficiently with each other. Fiber optic connectors like item 771000-2100 must be correctly placed to close open circuit ends and thus ensure the functionality of the system. When changes occur within the MOST system, such as the removal of defective components, proper handling and covering of the fiber optic cables is crucial to avoid disruptions or loss of functionality.

Can the ASA Mercedes Audiogateway MOST>Cinch be used with an OEM navigation unit?

Yes, the ASA Mercedes Audiogateway MOST>Cinch is compatible with specific OEM navigation units such as the Audio 50 APS Comand NTG2 / NTG2.5. These units require a direct adaptation to the MOST bus for system functionality. Vehicles equipped with Comand OEM navigation based on these NTG standards can thus continue to use their factory-installed sound system in combination with an external retrofit radio without any issues. However, it is crucial that the unit is properly integrated into the existing MOST ring to ensure error-free operation.

What happens with defective OEM additional components in the ASA Mercedes Audiogateway MOST>Cinch?

With defective OEM additional components such as a CD changer, TV tuner, or telephone system that are integrated into the MOST bus ring, these must be removed to avoid disrupting signal transmission. Open fiber optic ends can be closed with products like the fiber optic loop (f), item number 771000-2101. This prevents signal loss and allows the main system to continue being used without necessarily repairing the affected components. This way, the focus remains on the functionality of the amplifier and speakers.

Why is testing before the final assembly of the ASA Mercedes Audiogateway MOST>Cinch important?

Before the final assembly of the ASA Mercedes Audiogateway MOST>Cinch, it is essential to check all connections and functions to ensure that there are no installation errors that could lead to signal interruptions. A thorough check avoids later problems, especially with the fiber optic connections in the MOST ring, which must be correctly positioned and closed. This initial functional test helps to detect defects early and prevent unnecessary effort later on, ensuring a smooth installation and functionality of the entire audio system.
