Installation Guide
Preparation
1. Disconnect battery
Before you begin, always disconnect the
battery negative terminal.
Note:
If the unit is to be installed in a car equipped
with an on-board drive or navigation computer,
do not disconnect the battery cable. If the
cable is disconnected, the computer memory
may be lost. Under these conditions, use extra
caution during installation to avoid causing a
short circuit.
2. Remove unit from sleeve
Lift latches on both sides of sleeve to remove
half-sleeve from the unit.
Mounting Sleeve Installation
1. Slide the mounting sleeve off the chassis.
If it is locked into position, use the removal
tools (supplied) to disengage it.
2. Check the dashboard opening size by
sliding the mounting sleeve into it.
If the opening is too small, carefully cut or
file as necessary until the sleeve easily
slides into the opening. Do not force the
sleeve into the opening or cause it to bend
or bow. Check for sufficient space behind
the dashboard for the unit chassis.
This unit can be installed in any dashboard
with a suitable 183 mm (W) x 53 mm (H)
opening as shown above. The dashboard
should be 4.75 mm - 5.56 mm thick in order
to be able to support the unit.
3. Locate the series of bend tabs along the
top, bottom, and sides of the mounting
sleeve. With the sleeve fully inserted into
the dashboard opening, bend as many of
the tabs outward as necessary to firmly
secure the sleeve to the dashboard.
4. Place the unit in front of the dashboard
opening so the wiring can be brought
through the mounting sleeve. Follow the
Device Connections
Using the ISO Connector
1. If your car is equipped with the ISO
connector, then connect the ISO connectors
as illustrated.
2. For connections without the ISO
connectors, check the wiring in the vehicle
carefully before connecting, incorrect
connection may cause serious damage to
this unit.
Cut the connector; connect the colored
leads of the power cord to the car battery,
as shown in the color code table below for
speaker and power cable connections.
