Product Details

NAV-TV M650-GM Audio Interface Kit - NTV-KIT838

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 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 112dBAll warning chimes and audible turn signal indications are attenuated to factory levels and, along with Onstar®, Navigation prompts and Bluetooth, are passed to the proper output channels, 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, 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.

 For ease of use, the M650-GM is configurable through dip switch settings.  User selectable features of the M650-GM are:

 Factory Bass control becomes a Subwoofer Level Controller or Controls Bass for the entire system (Analog output only) – eliminates the need for a sub control knob!

  • Time alignment to driver (Full-Sized SUV and Truck Only) or no time alignment (Analog output only)
  • Loudness control for extended bass response at low levels or loudness off (Analog output only)
  • Digital Output at 24 bit 48 kHz or 24 bit 96 kHz (Digital outputs only. Refer to your DSP for compatibility with digital audio above 48 kHz)


  • The OPi-P with AUX kit adds iPod control and composite audio auxiliary audio to the factory fiber optic system in select Porsche vehicles.
