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 (white)
B4 – (-) front right (white/black)
B5 – (+) front left (gray)
B6 – (-) front left (gray/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.

ISO cable connections
1. Terminal plug
2. Fuses
3. ISO-plug
This plug connects the ISO cable
with the vehicle. The ISO cable as
such serves as an extension cable
for an eased connection of the unit
to the vehicle provided that the
vehicle has a standardized ISO plug
with the appropriate pin assignment.
Please note
»The multicore cable may vary depen-
ding on the current model. Though the
conguration of the loud speakers- and
power supply- cables (steady plus,
ignition plus, ground) is consistent.
»Certain patches could be possibly
found not only on the ISO interface
(socket/plug), but immediately on the
device, e.g. ports for the handbrake,
rearview camera, steering wheel
remote control etc.
»The ISO port may be already inte-
grated in certain units. In this case
an additional ISO cable becomes
unnecessary.

Common solutions
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.

ISO cable connections
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.
