be hidden under the dashboard. The LED indicator can be connected to the GPS U1
with the Communication cable included in the set.
4. External GPS antenna:
Although the GPS U1 has a built-in GPS antenna, in case of stealth installation (when
the device is installed under the dashboard) an external GPS antenna is required for
establishing connection with the GPS satellites. The GPS antenna can only operate
properly, if its upper side has a clear view to the sky.
5. RAD U1 radar detector module:
The RAD U1 module is able to detect the signals of both fixed and mobile radar-based
speed cameras. The module connects to the GPS U1 unit and it can be installed
behind the plastic bumper of a vehicle. Further information regarding the installation
and operation of the module are available in the user manual of the device.
6. Central unit of the D Ultimate laser module:
The D Ultimate laser module connects to the GPS U1 unit with the Communication
cable included in the set. The power supply of the whole system in ensured by the
laser module, therefore it must be connected into the electrical system of the vehicle.
Further information regarding the steps of the installation are available in this manual.
The laser sensors in the license plate frame (7. and 8.) connect to the central unit
of the laser module. Further information regarding the installation, update and
operation of the laser unit are available in this manual.
WARNING! If the complete system is installed, the GPS U1 is powered through
the Communication cable of the D Ultimate module, therefore no power cable
may be connected to the GPS U1 directly, because it may disturb and damage
the electrical system of the vehicle!
Due to the laser-muting features of the GPS U1, the beeping sound of the
laser module must be terminated. To do this, the buzzer of the laser module
has to be removed or its wirings must be disconnected from the 10-pin socket.
If the complete system is installed, the LED indicator of the laser
module may remain hidden under the dashboard with the central unit,
because the GPS U1 unit will give the alarms to the driver.
The central unit of the laser module and the GPS U1 device must be updated
and configured separately at first startup. In order to do this, always follow the
instructions found in the user manual and on the website of the manufacturer.
