Connecting RAA-5 External Antenna

To iWAY™ Automotive GPS units

This instruction sheet explains the proper method for connecting the
RAA-5 external antenna to iWAY™ automotive GPS units. The external
antenna is an optional accessory sold separately from the iWAY unit.

While the iWAY has a built-in antenna, the external antenna is avail­able for installations where satellite reception is poor. The external an­tenna was designed to work specifically with iWAY automotive GPS
units.

Caution:

If you do not connect the external antenna to your iWAY cor­rectly it could prevent the unit from successfully receiving satel­lite signals with the external antenna.

GPS units. The GPS antenna module can be mounted to any flat sur­face. The magnetic back allows the antenna module to be used on most
steel surfaces or you can peel back the liner and "stick" it to a selected

surface.

The GPS antenna has a magnetic back for mounting to metal surfaces.
If you prefer you can peel off the liner on the back of the antenna mod­ule and "stick" it to a selected surface.

The antenna cable has a male connector which attaches directly to the
iWAY unit. It is not necessary to configure the iWAY once the antenna
is attached. The iWAY will "read" the external antenna and should be­gin to receive satellite signals once the antenna is plugged into the
unit.

Caution:

Do not mount in line with a radar antenna. Radar radiates high
energy signals that can interfere with GPS signal reception.

The iWAY 250c external antenna socket allows for connection of an

external GPS antenna. The external antenna socket is located at the

far right of the unit. You will need to lift the protective cover to expose

the external antenna socket.

Be sure that a clear, unobstructed view of the sky is available at the
selected antenna module location. GPS signals travel "line-of-sight" at
very high frequencies, so nearly anything blocking the antenna can
stop the unit from finding a satellite.

In an automobile you may achieve good reception results by placing the
external antenna module on the dash at the base of the windshield. If
dashboard reception is poor relocate the antenna module somewhere on
the vehicle where it will have a clearer view of the sky.

an external GPS antenna. The external antenna socket is located at

the far right of the unit. The RAA-5 external GPS antenna plug is pic-

tured at right.
