GPS/Wireless System Wiring Diagram
3. Mount the GPS Module on top of the dashboard. Special requirements that
should be taken into account when mounting the GPS Module are:
•
Locate the module so that it has a clear view of the sky. Any metal
obstructions may interfere with satellite reception. Davis recommends
placing the GPS Module on the deep left corner of the dashboard. See
the graphic on the previous page for more information.
•
The module must be at least three (3) feet away from any cellular or CB
antenna. Close proximity to a transmitting antenna may degrade or
disrupt GPS reception.
4. Secure module by using two pieces of velcro tape or two pieces of double-
sided tape.
Note: Davis does not recommend mounting the GPS Module or Wireless On-Board Module
outside of the vehicle.
5. Route the GPS Module cable to the GPS/Wireless Interface Module and
plug the connector into the correct socket.
6. Mount the Wireless On-Board Module on a corner of a windshield. Special
requirements that should be taken into account when mounting the Wireless
On-Board Module are:
•
Locate the module in the upper left corner of the windshield so that it
won’t obstruct the driver’s field of view. Dress the cable down the left
side of the windshield glass.
•
Make sure the Wireless On-Board Module cable is mounted to the glass
with the cable at the top. This correctly orients the antenna within the
module.
•
Mount the module so that its nearest edge is at least 1'' from the left
windshield pillar.
•
The module must be at least three (3) feet away from any cellular or CB
antenna. Close proximity to a transmitting antenna may degrade or dis-
rupt wireless transmission.
7. Secure module by using two pieces of velcro tape or two pieces of
double-sided tape.
8. Route the Wireless On-Board Module to the GPS/Wireless Interface
Module and plug the connector into the correct socket.
