NAVtv M650-GM

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 GM vehicles with the Bose amplifier.  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.

The M650-GM produces a 6 channel analog output (Front L/R, Rear L/R, Sub and Center). 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 proper output channels, eliminating the need for an external speaker. 

NOTES: NON-BOSE vehicles are NOT COMPATIBLE with this kit.
