ZEN RCA Harness
NTV-HAR315
The NAV-TV ZEN-M processor seamlessly converts late model Mercedes factory MOST-150 audio bus to 12-
channel analog RCA and TOSLink output. Adding aftermarket amplifiers to the OE NTG5, 5.1, 5.2 or 5.5 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: vehicles not equipped with a factory amplified system must be
flashed with NAV-
TV’s
ZEN-M-PRG (NTV-KIT866, sold separately) prior to installation. Vehicles equipped with
an OEM amplifier do not need to be flashed.
