Owner's Manual

Guide your wire harness to your power source, in this case a power harness
located under the kick plate. (Pick
non critical connections such as interior
lights, never modules
or fuel pump). Use a volt meter to find your constant
power source (red cable batt+) which means this connection always has
12 volts
running through it even with ignition
off. Attach to line.
The blue wire in your accessory power source, this line only has power running
through it when the ignition
is on. Use your volt meter to determine which line
to attach. (Again never use critical fuse).
Dealership technicians
or professional aftermarket installers can tap into back of
fuse box. Note: when you tap directly into wiring check online for proper tap
points for vehicle specifics.
Some wiring comes from relays or distribution points and the voltage maybe
lessened for its destination. Use volt meter to check volt current to ensure its
above
12 volts closet to 13 volts as possible when running. The SmartNav will not
run as designed with anything less. Also keep in mind some cars may seem to
have a constant power supply. Wait
15 minutes after cars is off and recheck to see
if that constant source went to sleep and shutoff. SmartNav 5 uses it for memory.
It has internal battery for safety shutdown.
