ISO plug configuration

A B

Socket A (power supply)

On the A side you can find the socket for power supply.

A1 - spare

A2 - spare

A3 - spare

A4 - (+) 12Volt battery / steady plus *

A5 - electric antenna (+)

A6 - spare

A7 - (+) 12Volt ignition plus *

A8 - minus / ground (-)

* - 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 find the speakers terminals.

B1 - rear speaker right (+)

B2 - rear speaker right (-)

B3 - front speaker right (+)

B4 - front speaker right (-)

B5 - front speaker left (+)

B6 - front speaker left (-)

B7 - rear speaker left (+)

B8 - rear speaker left (-)

The terminals are coloured by pairs, in each case one (+) and one (-).

Though the design of ISO plug is standardized, it's pin assignment 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 description of features and functions that your model does not support.

The description of the problem	The cause and the solution
The remote control is without function.	Solution 1:Please ensure that the battery film is removed. By delivery the battery is protected by a film 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.Poor radio reception:The radio tuner finds nobroadcaster or the reception is poor.	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 assignment 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.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 (see page 33 – wiring diagram):We recommend you to substitute the existing antenna by the larger and therefore more efficient one.Shark fin or rod antennas (under 5 cm) are definitely insufficient.Type 2 – active antenna (see page 34 – wiring diagram):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 amplifier which is far less efficient.
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 (see page 10).Caution:If these wires have fuses the latter should be interchanged as well.
