CORAL SPRINGS, FL (09.06.2017) – NAV-TV Corp. has announced a revolutionary new amplifier integration solution that allows the seamless addition of aftermarket amplifiers into General Motors Vehicles equipped with MOST 50. With the M650-GM, you can now easily deliver the audiophile-quality sound your customers demand without compromising the vehicle’s factory fit, finish or features.

The M650-GM produces a completely flat audio output without any factory time delay or equalization, eliminating the need for summing devices, an audio correction DSP or the removal of the factory audio compensation microphones. It is 100% plug-and-play, installing at the factory tuner in both amplified and non amplified GM vehicles. Installation of the interface requires absolutely no modification to the vehicle or the removal of any factory equipment and can be used when completely replacing the factory speakers, or in any combination utilizing the factory audio components. Volume, Fade[1] and Balance are supported through the factory radio and steering wheel controls.

Utilizing a 128 bit per channel floating point DSP and 192 kHz 32 bit DAC, the M650-GM produces a 6 channel analog output (Front L/R, Rear L/R, Sub and Center) with a peak voltage of 6.3V and a S/N Ratio of 112dB. All warning chimes and audible turn signal indications are attenuated to factory levels and, along with Onstar, Navigation prompts and Bluetooth, are passed to the front output channels[2], eliminating the need for an external speaker. The unit provides a 500mA output for controlling aftermarket devices and, additionally, retains the factory 3 band equalizer (high, mid and bass).

For use with 3rd party digital sound processors[3], the M650-GM includes a variable Toslink (optical) and S/PDIF (coaxial) digital output which may be used simultaneously with the analog outputs, or by themselves. 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.
