5. Installation of the GPS/GSM antenna
The antenna delivered with the system is a two-piece combination
GSM/GPS antenna. The combination GSM/GPS antenna is a glassadhesive antenna; i.e. no leads must be run from the outside to the
vehicle interior.
Windscreen or rear window
D
E
The GSM/GPS combination antenna consists of an internal unit A and
an external unit B. To ensure correct function, the two units must be
installed as described below: Attached to the internal unit A is a 3-metre
long cable C with the combined GSM/GPS plugs. The connecting cable
is connected to the GSM/GPS Box with the GSM/GPS plugs. If more
than 3 metres of cable are required, the cable can be extended with the
optionally available extension cable (Stock No. 1380311). The antenna
D can be loosened F to adjust the angle E by twisting the antenna. After
loosening and adjusting, the antenna D must be screwed on hand-tight.
The angle of the antenna to the vehicle has an influence on
)
the antenna’s transmission and reception.
If reception is still unsatisfactory after installation, the
angle of the antenna to the vehicle can be adjusted to
optimise reception. In most cases, best results are achieved
with the antenna in a vertical position.

adhesive part is now exposed.
First adhere the external unit (A) with the slot at the top to the glass by firmly pressing (approx. 3-5 seconds)
around the circumference of the external unit base.
Subsequently, affix internal unit (B) to the inside of the window, once again by pressing on the housing of the unit
for approx. 3-5 seconds, with the circular area centred in the middle of the outside unit (centre point = centring
axis).
Depending upon the amount of space, the position of the internal unit can be turned on this centring axis before
being directly affixed.
The ideal adhesion temperature is between +15 °C and +25 °C.

The adhesive foil will adhere immediately to the adhesion surface and cannot be repositioned. It is not possible
to reuse the adhesive foil.

6. Installation of the hands-free microphone
The hands-free microphone should be placed in the vehicle to allow optimal recognition of the speaker’s voice. Possible
positions in the vehicle for the microphone can be seen in the following diagram.
The installation position should be as far away from the loudspeakers as possible. If problems occur, different
)
positions should be tested. In order to pick up as little background noise as possible, the microphone has a
narrow pick-up angle and must consequently be directed towards the driver.

B: Alternative installation position
C: Less suitable installation position
D: Speaking direction on microphone
E: Adhesive strip for affixing to smooth surfaces
F: Screw for fastening the screw-on plate
G: Screw-on plate for affixing to rough or uneven surfaces.
Affixing the hands-free microphone to a flat and smooth surface can be accomplished with the adhesive strip E (Clean
adhesion surfaces). If the microphone is to be affixed to a rough or uneven surface, the screw-on plate G should be affixed
first with the screw F (To avoid risk of damage, please pay attention to screw length). Subsequently, affix the microphone
to the screw-on plate G with the adhesive strip E. The connection of the hands-free microphones takes place in socket C
of the OnlinePro.

integrated. An installation frame is not required. The unit is inserted into the installation slot and secured with the slides supplied.
To install, complete all electrical connections. Then push the unit
into the installation slot. Subsequently, insert slides into the openings on the front of the unit until the first detent position (Fig. A).
Now lock the radio in by pulling on both slides as shown in Fig. B.
Subsequently, remove the slides.
The installation angle of the unit must not exceed 0° - 35°
)
(vertical).
•Removal:
To remove the unit, it must first be unlocked. For this purpose,
push in both slides to the second detent position, as shown in Figure A. Subsequently, withdraw the unit with both slides. (Fig. C).
Then remove the slides by pressing the springs on the right and left
sides of the unit.
If the unit was installed previously in another vehicle, it may be
necessary to adjust the springs on the unit before installation. To
adjust the springs, insert slide as shown in Fig. D and subsequently
adjust as shown in Fig. E (Gently press slide in the direction of 1
while at the same time moving the slide in the direction of 2).

12. Calibration
•After voice installation, you will have to wait for GPS reception
before beginning the calibration journey.
During this reception check, the vehicle must be in an open area
and the GPS antenna must have as clear a view as possible in all
directions. It may take a few minutes until adequate GPS reception
is available. The next display appears during this period. A calibration journey is requested when sufficient GPS reception is available.
In order to minimise the waiting period for sufficient GPS
)
reception, the vehicle should not be moved during this time.
The unit must be switched on.
Before beginning the calibration journey, the sensors tests described in
"Service Mode" on page 52 must be performed.
To call up the Service Mode, press and hold the multifunction
button. Now press the multifunction buttons .
The Service Mode will be called up.
After successful completion of the tests, the calibration journey can
begin.
Exit the Service Mode by pressing the key.
After commissioning, a calibration journey is required. During this
journey, the speedometer signal (GAL) is adapted to the vehiclespecific data, and the gyro-sensor to the unit installation position.

15. Troubleshooting
Troubleshooting for GPS antennas and faulty installation
Fault: Permanent or temporary interference with GPS reception, faulty determination of current position, unit cannot be
calibrated.
The navigation system calculates the current position from the data received by the integrated GPS satellite receiver. Perfect GPS reception is very important for the proper functioning of the navigation system. Reception is strongly affected
by the installation position of the antenna.
The antenna should not be installed under metallised windows and should, as far as possible, have a "free view" of the sky.
It is possible to check how many satellites are being received via the GPS info menu. See “Function control of the GPS
antenna (GPS info)” on page 54.
On average, more than 4 satellites should be received. It is not, however, merely the number of satellites which is decisive,
but also the quality of the reception signal. Quality of reception depends on the weather, so that in the case of installations
without sufficient reception potential, trouble-free navigation is possible in good weather conditions, whereas navigation
may not always function faultlessly in poor weather conditions.
This behaviour often occurs when the reception antenna is fitted behind coated windows (e.g. Siglasol or other heat-protection glazing).
One indicator for poor GPS reception quality is a rapid change in the number of receivable satellites, where these cannot
be accounted for by reception shading (buildings, bridges, trees or tunnels).
Solution: The most favourable installation position possible should be selected. In the case of all-round heat-reducing glazing, an exterior antenna connected via an adapter (optionally available) can be used.
Subject to errors or technical changes58Copyright by Becker GmbH, D-76303 Karlsbad
Page 29
Installation Guide
Noise with external power amplifier (end stage)
Fault: Noise can be heard in conjunction with an external power amplifier.
Possible solutions:
•Use the line-out rather than the loudspeaker output connections for output to the external power amplifier.
•Correct setting of the sensitivity of the power amplifier at the unit's output.
Set the input level of the amplifier to approx. 3 Volt (3000mV) for this purpose.
In the case of a sensitive power amplifier input (e.g. 100mV) where no level adjustment is possible, an attenuator
must be interposed.
Echo during phone calls
Fault: The other party hears an echo during phone calls.
Solution: Set the sensitivity of the hands-free microphone (see Operating Guide, under User Menu). In most cases, a
setting between 0 and 3 achieves an optimum result.
