Press Release (edited):
NAV-TV announced its new pre-amp/interface now works with Mercedes-Benz vehicles using the MOST 150 system. It joins similar interfaces from NAV-TV for Volkwagen, Audi, Porsche, Bentley and GM vehicles.
The ZEN-M allows users to keep their factory radio and add an aftermarket amplifier. It produces a flat audio output, eliminating factory time delay and equalization, so there’s no need to install a summing device or an audio correction DSP or to remove the factory audio compensation microphones.
Installation of the interface requires no modification to the vehicle. It is compatible with both amplified and non amplified factory systems. Volume, Fade, Balance and Bass/Treble tone controls are retained through the factory radio and echo cancelation for the factory Bluetooth hands-free system is supported.
Using a 128 bit floating point DSP and 192 kHz 32 bit DAC, the ZEN-M produces a 12 channel analog output with a S/N Ratio of 123dB. For vehicles with video playback capability, the ZEN-M supports 7.1 and 5.1 audio[2]. The unit provides a 500mA output for controlling aftermarket devices and, additionally, retains the factory equalizer.
For use with 3rd party digital sound processors, the ZEN-M includes a variable TOSlink digital output which may be used simultaneously with the analog outputs, or by itself. The variable digital output allows for the system volume to be controlled via the factory radio and steering wheel controls without the need to access any 3rd party controller.
The ZEN-M is currently shipping. It supports the following Mercedes Benz models with NTG5, NTG5*1, NTG5*2 and NTG5*5 infotainment platforms:
