M650-GM Interface
NTV-ASY264
NAV-TV’s M650-GM processor seamlessly converts GM’s MOST-50 audio bus to low level (6 channel) RCA,
S/PDIF or TosLink outputs. Adding an aftermarket amplifier to the OE IO5/IO6 system has never been 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 (true OEM integration).

M650-GM Installation
1. Use the chart on page 3 to locate the OEM radio tuner. Remove all panels/dash pieces to access the
plugs on the OEM radio tuner.
2. Using the provided T-Harness, connect between the proper
connectors (gray 20-pin & gray 8-pin) at the OEM radio tuner
and OEM harness’ from the vehicle.
3. Before connecting power to the M650-GM,adjust dip-switch settings for the desired options:
4. If using analog RCAs to connect to the amplifier, connect FRONT, REAR, SUB/Center to RCA connectors
as shown on page 2. 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 S/PDIF for signal to the amplifier, connect to either TosLink or Coaxial connector shown on
page 2. NOTE: both Analog and Digital output sound simultaneously, regardless of which type is used.
6. Use the provided blue wire (extend) for amplifier turn on. NOTE: this wire must be used for amp turn
on, instead of ACC as the amplifier(s) must wake before ignition (for door chimes, etc). This wire will
output 12v whenever a door is unlocked (via remote) or opened (data-sensing). Make certain this wire
will not short circuit anywhere as it will have power any time the vehicle network is active.
