NAV Audio Source
Please read this manual and the GARMIN
ZUMO 660 NAV MP3 information
provided with your player to become
familiar with all unit features and operation.
The audio integration kit must be installed
to enable outputs from the NAV MP3 (such
as navigation instructions or user-loaded
MP3 media files) to play through the
headsets or speakers. The unit is fully
functional without the kit installed, but there
will be no interface with the vehicle’s audio
system.
Navigation MP3 Operation Tips
• Signals coming from the NAV MP3 unit will
override any source of the motorcycle’s audio
system to ensure navigation instructions are
communicated when needed. The signals will
also override the MP3 player.
• You must set volume levels within the NAV
MP3 unit. Volume settings in the motorcycle’s
audio system control NAV MP3 volume, but
navigation instructions may be difficult to hear
if volume levels in the unit are set too low. See
the GARMIN information for setting
procedures. The recommended initial settings
are 100/80/80: MASTER 100%, NAVIGATION
80%, MEDIA 80%.
• Pause or stop the MP3 player to play audio
from radio source.
• If playing MP3 files from the GARMIN ZUMO
660 unit, you may need to turn down the
“media volume” on the GARMIN unit to avoid
distortion.
• NAV audio must be turned on in the mode
menu in order to play MP3 music files from the
GARMIN ZUMO 660 NAV unit.
• While in NAV source, only MP3 music stored
on the GARMIN ZUMO 660 will play on the
radio.
The power switch must be ON to use the
audio system.
1. Press and release
until NAV is the
active source.
2. When navigation instructions are given,
the music volume will be muted and
“NAV” will be displayed in display
zone two.
