Poor radio recep-
tion:
The radio tuner nds
no broadcaster or the
reception 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 efcient one.
Shark n or rod antennas (under 5 cm) are denitely 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
amplier which is far less efcient.
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 interchanged as
well.
