same ground (-) as the stereo for this
signal wire to function correctly.
Activates when connected to ground.
For example, when you connect this wire
to a compatible, hands-free mobile kit,
the audio mutes or the input switches
to Aux1 when a call is received and the

Power Connection
When connecting the stereo to power, you must connect the yellow, red, and
black wires to the power source. The yellow and red wires have different
functions, and the method you use to connect them to power depends on
how you plan to use the stereo on your vessel.
Yellow wire
• This wire provides power to the stereo.
• This wire should be connected through a 15 A circuit breaker, if one is
available on the vessel.
If a 15 A circuit breaker is not available on the vessel, you must
connect this wire to power through a 15 A fuse (not included).
