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 (unless it is MIB3.) 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/MMI 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). For an MIB3 System, only the MIB Programmer (NTV-Kit 996) must be used.

3. Vehicles with MIB3 or without an 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 as shown below (to continue proper MOST data flow):

*NOTE: in this scenario, the vehicle still must be programmed for external amp (see red note

above).

• 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.
