tions to professional technicians.
Due to flawed warranty seal the warranty becomes invalid.

Power supply
Use the unit connected only to 12 Volt on-board power supply. The minus (-) should be connected with the ground (GND) (negative).
Due to the wrong grounding exists the danger of fire. In case of doubt please consult with professional technicians.

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 fire.

ISO cable connections

!We recommend you to let a professional technician install the unit in your vehicle.
Terminal plug
This plug connects the ISO cable with the unit.
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.

ISO plug configuration

Socket A (power supply)
On the A side you can find the socket for power supply.
A1 - spare
A2 - spare
A3 - spare
A4 - +12V battery / steady plus (yello)*
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 find 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 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.

Please note
»The multicore cable may vary depending on the current model. Though the configuration 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 integrated in certain units. In this case an additional ISO cable becomes unnecessary.

| Poor radio reception:The radio tuner finds nobroadcaster or therecep-tion is poor. | For problem-solving regarding the radio reception itis important to know the type of the antenna of yourvehicle.Here are the possible solutions for each type of theantenna:Type 1 – passive antenna:We recommend you to substitute the existing antenna bythe larger and therefore more efficient one.Shark fin or rod antennas (under 5 cm) are definitelyinsufficient.Type 2 – active antenna:The vehicle provides no current for the active antenna.In this case a phantom power is required, which providesthe active antenna with the external power supply.Type 3 – active antenna with diversity system:The unit provides no current for the active antenna andhas no diversity support. For this type of antenna isrequired the phantom power with an integrated diversitysystem.Note:A phantom power is not to be confused with an antennaamplifier which is far less efficient. |
