Page 5: Installation Of The Gps Antenna
Installation Guide Installation of the GPS antenna Risk of injury People with pacemakers should avoid proximity to the magnetic antenna and should not carry the antenna on their person, as this may affect the function of the pacemaker. Keep the magnetic antenna away from data storage media (disks, credit cards, magnetic cards etc.) and electronic and precision engineering equipment, as this may cause data to be deleted. - Page 6 Installation Guide • Inside the vehicle The GPS antenna is not suitable for installation in vehicles with anti-glare windows (metalised thermo-glass or metal foil (can be seen on the window label - SIGLA SOL, SIGLA CHROM, SIGLA, KOOL-OF, SUNGATE, etc.) and vehicles with fine-meshed heating wires in the windows. Information on installation position When selecting the installation position, ensure that the antenna has a clear view in all directions, and that it is not covered by the windscreen wipers.

Page 8: Installation Of The Microphone
Installation Guide Installation of the microphone The 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, and as near to the speaker, as possible. If prob- lems occur, different positions should be tested. - Page 9 Installation Guide If the microphone is to be affixed to a rough or uneven surface, the screw-on plate F should be affixed first with the screw E. (To avoid risk of damage to any cables installed underneath or other vehicle components, please pay attention to screw length.) Subsequently, affix the microphone to the screw-on plate F with the adhesive strip D.
