Can I use the eTrex indoors?
No. The DEMO mode is available, but we suggest that only dealers use it.
Do I need to subscribe to a service to use the eTrex?
No. The GPS satellites are owned by the United States Department of
Defense (DoD) and have been funded by U.S. taxpayers’ dollars.
Reception of GPS satellite signals is free to everyone.
Does the eTrex work anywhere in the world and in any
weather?
Yes.
How accurate is a GARMIN GPS?
The eTrex is accurate to within 100 meters under the DoD-imposed
Selective Availability (S/A). Without S/A, the eTrex is accurate to within
15 meters. Using differential techniques, the eTrex can be as accurate as
1-5 meters.
Why can’t I see the display in the daylight?
Adjust the contrast (see page 9).
Why can’t I interface my computer with the eTrex?
Make sure that you have the correct INPUT/OUTPUT format selected on
your eTrex.
