5.0
Owner's of the Garmin GPS Receiver nüvi gave it a score of 5.0 out of 5. Here's how the scores stacked up:
During route navigation, it is sometimes desirable to navigate a specified distance
away from the ‘active leg’ to help avoid certain airspaces or regions. The GNC 250’s
parallel track feature will automatically guide you along a selected offset from the
active leg.
To use offset navigation, or parallel track:
1. Press
R
and use
O
to display the route catalog page.
2. Use
K
to display route 0 (parallel track can only be used on the active route).
3. Press
C
twice and use
O
to highlight the parallel track value field.
4. Use
K
and
O
to enter the desired distance and direction (R or L) from the leg.
5. Press
E
to accept.
It is important to note that offset navigation is only available on route navigation,
not direct-to navigation. When offset navigation is activated, an ‘Offset nav in effect’
message will be displayed with the distance and direction noted on the route catalog
page for route 0. If you enter an offset which causes a leg to be reversed, you’ll be
informed with the message ‘Ofst too big for rte’. If you change the active route in any
way or perform a direct-to, you’ll be informed with an ‘Offset nav cancelled’ message.
