Installation
1. DIN Front-mount (Method A)
Notes:
- Choose the mounting location where the unit
will not distract the driver.
- Before finally installing the unit, connect the
wiring temporarily and make sure it is all
connected properly and the unit and the
system works properly.
- Use only the parts included with the unit to
ensure proper installation. The use of
unauthorized parts can cause malfunctions.
- Consult with your nearest dealer if
installation requires the drilling of holes or
other modifications to the vehicle.
- Install the unit where it does not get in the
driver's way and cannot injure the passenger if
there is a sudden stop.
- If installation angle exceeds 30° from
horizontal, the unit may not provide optimum
performance.
- Avoid installing the unit where it would
be subject to high temperature, such as
from direct sunlight, or from hot air from
the heater, or where it would be subject to
dust, dirt or excessive vibration.
DIN Front/Rear-Mount
This unit can be properly installed either
from 'Front' (conventional DIN Frontmount) or 'Rear' (DIN Rear-mount
installation, utilizing threaded screw
holes on the sides of the unit chassis).
For details, refer to the following
illustrated installation methods.
Installation opening
This unit can be installed in any
dashboard with an opening as shown
below:
Installing the unit
Be sure you test all connections first, and
then follow these steps to install the unit.
1. Make sure the ignition is turned off,
and then disconnect the cable from the
vehicle battery's negative (-) terminal.
2. Disconnect the wire harness and the
antenna.
3. Press the button (1) on the front
panel and remove the control panel (for
details, refer to 'Using the Detachable
Front Panel', page 4).
4. Lift the top of the outer trim ring, then
pull it out to remove it.
5. The two supplied keys release tabs
inside the unit's sleeve so you can
remove it. Insert the keys as far as they
will go (with the notches facing up) into
the appropriate slots at the middle of the
left and right sides of the unit. Then slide

6. Mount the sleeve by inserting the
sleeve into the opening of the dashboard
and bend open the tabs located around
the sleeve with a screwdriver. Not all tabs
will be able to make contact, so examine
which ones will be most effective. Bend
open the appropriate tabs behind the
dashboard to secure the sleeve in place.

7. Reconnect the wire harness and the
antenna and be careful not to pinch any
wires or cables.
8. Slide the unit into the sleeve until it
locks into place.
9. To further secure the unit, use the
supplied metal strap to secure the back
of the unit in place. Use the supplied
hardware (Hex Nut (M5mm) and Spring
Washer) to attach one end of the strap to
the mounting bolt on the back of the unit.
If necessary, bend the metal strap to fit
your vehicle's mounting area. Then use
the supplied hardware (Tapping Screw
(5x25mm) and Plain Washer) to attach
the other end of metal strap to a solid
metal part of the vehicle under the
dashboard. This strap also helps ensure
proper electrical grounding of the unit.
3. Press the release button to remove the
front panel.
4. Lift the top of the outer trim ring and
then pull it out to remove it.
5. Insert both of the supplied keys into
the slots at the middle left and right sides
of the unit then pull the unit out of the
dashboard.
2. DIN Rear-mount (Method B)
If your vehicle is a Nissan or Toyota,
follow this mounting instruction. Use the
screw holes marked T (Toyota) or N
(Nissan) located on both sides of the unit
to fasten the unit to the factory radio
mounting brackets supplied with your
vehicle.
10. Reconnect the cable to the vehicle
battery's negative (-) terminal. Then
replace the outer trim ring and install the
unit's front panel (see the steps of
'Installing the Front Panel', page 4).
Removing the unit
1. Make sure the ignition is turned off,
and then disconnect the cable from the
vehicle battery's negative (-) terminal.
2. Remove the metal strap attached to
the back of the unit (if attached).
Align the screw holes on the bracket with
the screw holes on the unit, and then
tighten the screws (5x5mm) on each
side.
Note: the outer trim ring, sleeve and
the metal strap are not used for
method B installation.
