problems.
Leave all the repair operations to
professional technicians.
Due to awed warranty seal the
warranty becomes invalid.
!
Power supply
Use the unit connected only to 12 Volt
on-board power supply. The minus (-)

(GND) (negative).
Due to the wrong conguration exists
the danger of re. In case of doubt
please consult with professional techni-
cians.
!
Replacement of fuses
While replacing the fuse please make
sure that the new fuse has the same
properties as the old one, especially the
amperage.
!
Overheating
Do not occlude the vent holes to avoid
the heat generation and accumulation
in the unit. Otherwise exists the danger
of re.
!
Regular temperature
Before switching on the device, make
sure that the inside temperature in
the vehicle is not below 0°C or above
+40°C.
If it's too cold or too hot inside of the
vehicle, do not turn the unit on until
the inside temperature of the cabin
descends.

To avoid the risk of losing the warranty
please let a specialist accomplish the
installation of the unit.
»To avoid a short circuit please
disconnect the vehicle battery before
the installation. To do it properly please
read the manual of the vehicle.
»Please be aware that this unit has an
2DIN standart size. Make sure that your
vehicle is equipped with an installation
cell of required size.
»As may be the case you will need a
suitable faceplate, adapter or other
accessories. These could be provided
from your local specialist supplier.
»The connection cables may not be
cutted or short-circuited. Otherwise the
warranty becomes invalid.
»Before the installation please make
sure that the vehicle has the 12 Volt
on-board power supply.
We recommend you to let a
professional technician install the
unit in your vehicle.
!
!
»The minus (-) should be connected
with the ground (GND) (negative).
»Please tag the polarity of the avai-
lable speakers before you disconnect
the vehicle battery.
»A proper grounding of the unit's
housing requires a clean ground
connection. Thus the grounding area
should be rust-, stain- and dust-free.
»Please ground the cable separately
from other heavy current devices such
as an amplier etc.
»Please ensure that the coloured
cables are connected according to the
wiring diagram. The wrong wiring may
lead to malfunctions or even damages
of the electric elements of the vehicle.
»Please note that the connection
cables of this unit and of the other
devices may have the same purpose
but the different colour. For this reason
while connecting this unit with the
other devices please ensure that both
of the cables in each case have the
same purpose. To congure everything
correctly please refer to the manuals of
the both devices.
»Please ensure that the negative
speaker cable is in each case plugged
into the negative speaker socket of the
ISO interface. Do not ever connect the
negative speaker cables with the vehicle
body.
»This unit is designed and construed
for connection with 4 speakers. Do not
combine this unit with devices that are
designed and construed for connection

with 2 speakers.
»The speakers should feature the
impedance of 4-8 Ohm and a sufcient
wattage.
»Please ensure that the speakers you
are connecting with the unit are intact.
Damaged speakers can impair the unit.
»To avoid a short circuit please isolate
all cable junctions and endings of the
unused cables with the electrical tape.
»All the cables should be layed and
xated tidy and properly. The cables
should not contact any movable or hot
objects.
»If the vehicle doesn't have an "ACC"
ignition position, please connect the
red cable with the ignition switch.
Otherwise the unit does not turn off
automatically, causing the discharging
of the vehicle battery.
»To avoid a rogue and hazardous
short circuit do not lay the yellow cable
through the engine bay in order to
connect it with the vehicle battery.
»Do not ever connect speaker cables
among one another. In case you do not
want to connect all the 4 speakers with
the unit please isolate the endings of
unused cables with the electrical tape
to prevent a short circuit.
»Do not ever connect the negative
speaker cables with the vehicle body.
»To ensure a awless performance of
the unit the intergration angle should
amount to +/- 30.

Socket A (power supply)
On the A side you can nd the socket
for power supply.
A1 – spare
A2 – spare
A3 – spare
A4 - (+12Volt) steady plus * (yellow)
A5 – (+) electric antenna (blue)
A6 – spare
A7 - (+12Volt) ignition plus *(red)
A8 – (-) minus / ground (black)
* - Some vehicle manufacturers use
their own pin assignment. Especially
the terminals A7 (ignition plus) and A4
(steady plus) are often interchanged.
The incorrect connection in this case
leads to following problem: the unit
can not be turned on if the ignition is
off and all the saved settings are lost
as soon as the unit will be turned off. If
these problems appear the connections
A4 and A7 should be interchanged.
Socket B (loud speakers)
On the B side you can nd the speakers
terminals.
B1 – (+) rear right (violet)
B2 – (-) rear right (violet/black)
B3 – (+) front right (gray)
B4 – (-) front right (gray/black)
B5 – (+) front left (white)
B6 – (-) front left (white/black)
B7 – (+) rear left (green)
B8 – (-) rear left (green/black)
The terminals are coloured by pairs, in
each case one (+) and one (-).
Though the design of ISO plug is
standardized, it's pin assigment is not
and may vary. Thus in case of mis-
match of connections due to different
pin assignments a simple plug'n'play
connection may lead to grievous errors.

Common solutions
https://www.xomax.de
The describtion of the
problem
The cause and the solution
The remote control is
without function.
Solution 1:
Please ensure that the battery lm is removed. By
delivery the battery is protected by a lm which should
be removed before usage.
Solution 2:
The battery could be empty. Please replace it if required.
Solution 3:
Please make sure that the infrared receiver (labelled with
IR) on the control panel is not blocked.
Note:
You can test the functionality of the remote control as
follows: please hold the IR transmitter towards a camera
(e.g. a cell phone camera) and press any button on the
remote control. If the remote control is operative you
can see the infrared signal on the display of the used
camera device.
The unit does not turn
on.
This problem is in most cases caused due to a wrong
connection of the ISO cable.
Please review the pin assignments of the ISO cable and
ISO plug. Pay attention to the proper connection of the
ignition- and steady plus and correct the discrepancy if
required.
Note:
Though the design of ISO plug is standardized, it's pin
assigment is not and may vary. Thus in case of mismatch
of connections due to different pin assignments a simple
plug'n'play connection may lead to grievous errors.
Common solutions
The following advices are generally valid and refer to diverse Xomax models with
the similar characteristics. Please note that some articles may refer not to your
model exactly and contain the describtion of features and functions that your model
does not support.

Poor radio reception:
The radio tuner nds no
broadcaster or the recep-
tion is poor.
For problem-solving regarding the radio reception it
is important to know the type of the antenna of your
vehicle.
Here are the possible solutions for each type of the
antenna:
Type 1 – passive antenna:
We recommend you to substitude the existing antenna
by the larger and therefore more efcient one.
Shark n or rod antennas (under 5 cm) are denitely
insufcient.
Type 2 – active antenna:
The vehicle provides no current for the active antenna.
In this case a phantom power is required, which provides
the active antenna with the external power supply.
Type 3 – active antenna with diversity system:
The unit provides no current for the active antenna and
has no diversity support. For this type of antenna is
required the phantom power with an integrated diversity
system.
Note:
A phantom power is not to be confused with an antenna
amplier which is far less efcient.
Radio stations are lost:
As soon as the unit will be
turned off all the stored
stations and users settings
will be lost.
This problem is caused due to a wrong connection of the
ISO cable.
Please interchange the cables for ignition plus and for
steady plus.
Caution:
If these wires have fuses the latter should be interch-
anged as well.
