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 efficient one.
Shark fin or rod antennas (under 5 cm) are definitely
insufficient.
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
amplifier which is far less efficient.
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.
