Antenna Location
In order for GPS to function correctly, the GPS antenna must have a clear view of the sky in
order to receive data from the satellites. Should this view be obscured, e.g. the vehicle is parked
in a metal-clad building then the performance of the T22 platform may be impeded. Wherever
possible it is preferable to park the vehicle in a location where the antenna will have a clear all
round view of the sky at installation time to test the signal strength.
The antenna and wires can be hidden from view but the installer.
Common locations are:
•Under the dashboard as far to the front of the vehicle as possible
•Under the plastic cover near the windshield wipers
•Under the plastic cover of the front or rear bumpers
•In the license plate lamp (on SUV types)
•In the side mirrors (when space permits)
Personal Assistance Button Location
It is recommended that the Personal Assistance Button, where fitted, is located within easy reach
and visibility of the vehicle driver, or where required in a covert location. Typically it will be fitted
into a blank switch position.
