Garmin GPS 100 - Manual (Page 11)

In order to track GPS satellites, the unit must be situated with the antenna
pointed straight up and should not be blocked by objects or people (signal
reception through thin fabric such as canvas may be adequate but degraded).
A wrist strap is provided to prevent accidental dropping of your GPS 100.
(Connect the wrist strap to the eyelet on the back of the unit.)
Gimbal Mount Operation:
A gimbal mount is supplied for fixed installation in a boat or land vehicle. The
unit may be operated using vehicle power through the power/data cable or
it may be operated using the battery pack.
While using vehicle power, you may wish to leave the battery pack in the unit.
Vehicle power will automatically maintain the rechargeable battery pack at
full capacity. In the event of vehicle power failure, the GPS 100 will
automatically switch to battery power.
In addition to supplying power to the unit, the power/data cable allows you to
interface your GPS 100 with other marine electronic devices such as plotters
or autopilots (see Section 14.2 on electrical wiring).
