The NAV-TV ZEN-V processor seamlessly converts late model AUDI, VW, Porsche & Bentley factory MOST-150
audio bus to 12-channel analog RCA and TOSLink output. Adding aftermarket amplifiers to the OE MIB, MIB2
or PCM4 / 4.1 system has never been so simple and seamless. This kit integrates with the OEM M.O.S.T.® bus
to retain volume control, full fade and balance (analog only), treble, mid-range, bass control & Bluetooth voice
calls with no external speaker (true OEM integration). NOTE: OEM radio systems not equipped with an
amplifier or fiber must be flashed with the VAG-COMM or NAV-TV’s ZEN-V-PRG (NTV-KIT861, sold separately)
prior to installation. Vehicles equipped with an OEM amplifier do not need to be flashed.

ZEN-V Installation
1. If this vehicle has a factory amplifier, it must be removed and the ZEN-V can be installed into its place.
If this vehicle is not amplified from factory, install the ZEN-V behind the radio.
2. Connect the following wires from the
provided power harness:
3. Before connecting power to the ZEN-V, adjust dip-switch settings for the desired options:
4. If using analog RCAs for signal to the amplifier, connect according to the reference chart below.
WARNING: Do not connect RCA cables to this interface until all amplifiers/external processors are
properly grounded. Failure to do this may cause damage to the interface and VOID the warranty!

5. If using TOSLink for signal to the amplifier, connect the cable to the TOSLink port shown on page 2.
NOTE: both Analog and Digital output sound simultaneously, regardless of which type is used.
6. Connect the provided MOST Fiber Cable from the (previously removed) amplifier, or from the radio’s
fiber port to the MOST port on the ZEN-V.

*NOTE: in this scenario, the vehicle still must be programmed for external amp (see red note above).
ZEN-V General Installation Notes
•This interface can be installed in vehicles with or without an amplifier & with or without MOST fiber
optic presently installed.
1. Vehicles with fiber amplifier: the amplifier must be removed. Connect the OEM fiber previously
connected to the amp, directly into the ZEN-V.
2. Vehicles without OEM amplifier or MOST fiber: Use the supplied fiber optic extension and
connect from the fiber port behind the radio to the MOST fiber port on the ZEN-V. NOTE: If the
vehicle does not possess an OEM amplifier, you must program the system for external amplifier
for the ZEN-V to operate properly. Use a VAG-COM or NAV-TV’s ZEN-V-PRG programmer (NTV-
KIT861 sold separately).
3. Vehicles without amplifier but still equipped with fiber: Disconnect the fiber from the radio,
disassemble the fiber coupler and route the provided MOST extension into the factory MOST
loop like shown below (to continue proper MOST data flow):
•Tuning tips:
1. Before beginning tuning process (especially with external EQ/Processors), set Bass & Treble on
the head unit for each source to flat (0).
2. Begin with amplifier/EQ gains all the way down.
3. With dynamic music playing, adjust the radio volume to maximum.
4. Adjust the amplifier/EQ gains to desired maximum level.
•From the factory, some vehicles’ audio will attenuate when in reverse. Simply set the ‘reverse volume’
to desired level while in reverse to adjust this. The ZEN-V will retain this method. The same is true for
NAV guidance audio and BT voice calls.
