Utilizing the same processing power as NAV-TV's other competition proven ZEN products, the ZEN-AVB  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. 

The ZEN-AVB produces a 6 channel analog output with a S/N Ratio of 112dB. A true audiophile pre-amp.

NAV-TV’s AVB-GM processor seamlessly converts GM’s AVB bus to low level (6 channel) Analog RCA or TOSLink outputs.  Adding an aftermarket amplifier to the OE BOSE system will never be so easy or seamless.  This plug & play kit integrates with various OEM data networks to retain OnStar, door chimes, volume control, full fade and balance (analog only), treble, mid-range, bass control & Bluetooth voice calls with no external speaker (for true OEM integration).  NOTE: the OEM amplifier must be present, then disconnected to maintain proper functionality.
