DES
The NAV-TV ZEN-25 processor seamlessly converts BMW factory amplied CCC, CIC, NBT and EVO systems to
12 channel analog RCA and single stereo Toslink output. Adding aftermarket ampliers to the OEM CCC, CIC, NBT
& EVO systems has never been so simple. This kit integrates with the OEM M.O.S.T. ® 25 bus to retain volume
control, full fade (analog only), balance, treble, bass control & 7 band eq. Note: OEM infotainment systems MUST
have a M.O.S.T. 25 factory amplied system for the ZEN-25 to work out of the box. Vehicles without a factory
M.O.S.T. 25 amplier must be programmed for an OEM amplier prior to the installation of the ZEN-25.
Programming is NOT supported by NAV-TV.

Fiber Installation in Vehicles with an Existing M.O.S.T. Amplier
1) Locate the factory amplifier, push down on the retaining clip and remove the harness containing the M.O.S.T.
connector from the amplifier
2) Gently pry the M.O.S.T. retaining clip towards the outside of the factory connector and pull the male fiber
optic out of the factory housing. Be careful not to leave grease or debris on the fiber optic cable ends.
3) This is what the male fiber optic should look like when removed from the factory harness
4) Insert the included M.O.S.T. Connector (NTV-CON002) over the factory male fiber optic end
5) This is what the fiber optic cable should look like once completed.
ZEN-25 Installation
If the vehicle has a factory M.O.S.T. ber optic amplier, it must be removed and the ZEN-25 can be installed in its
place. M.O.S.T. BMW ampliers are located in the left rear section of the trunk.

Wire Side
1) Connect the following wires from the
provided power harness:
*This 12v+ remote output wire MUST be used for the aftermarket amplier/DSP remote turn on for proper
functionality. If installing more than one Amp/DSP, a relay must be used for reliable system turn on.
2) If using analog RCA outputs for signal to the amplier, connections are made according to the chart below.
WARNING: Do not connect RCA cables to this interface until all ampliers /DSP are properly grounded.
Failure to do this may cause damage to the interface and VOID the warranty!
3) If using Toslink for signal to the amplier, connect the cable to the Toslink port shown on page 2. NOTE: both
analog and digital ouputs are aligned to produce sound simultaneously.
4) Connect the M.O.S.T. ber optic cable to the M.O.S.T. 25 connector on the ZEN-25 interface.

System Setup
Before setting gains on the aftermarket ampliers or DSP, you MUST follow the steps below:
1. Set the factory Bass & Treble on all sources to at (0).
2. If the vehicle has a 7 band EQ set it to at (0) as well.
3. Turn the amplier and DSP input and output gains to zero (all the way down).
4. With dynamic music playing, adjust the radio volume to MAXIMUM!
5. Adjust the amplier and DSP input and output gains to the desired maximum level.
NOTE: From the factory, some vehicle will attenuate audio when in reverse. The ZEN-25 will retain this OEM
feature. The same is true for Nav guidance and phone calls.
