Garmin GNC 250XL User manual

The difference
between Garmin’s
GPS/maps and all
others is like day
and night.
GNC 250XL/GPS 150XL
GARMIN’s newest entries in panel-mount technology stand in
sharp contrast to all challengers. The GNC 250XL is a
GPS/Comm with high definition moving map graphics. The
GPS 150XL is its no-Comm sibling. Each offers pilots a unique
combination of performance, convenience, price and clarity —
day or night.
As the only VFR panel-mounted units with GARMIN’s
proprietary 12-parallel channel GPS receiver (tracking 12
satellites simultaneously), the GNC 250XL and GPS 150XL lock
on fast and stay locked on for precise navigation information.
The GNC 250XL also delivers clear communication from its 760-
channel VHF transceiver. And both units feature front-loading
data cartridges for easy Jeppesen updating.
While these features made the original GNC 250 and GPS 150
industry leaders, the “XL” versions add incredible mapping
detail. The DSTN, double super twist nematic, LCD provides
more than two times the pixels of other panel-mount maps. So
jagged lines disappear and curved lines and alphanumeric
characters shine. A built-in photocell automatically adjusts the
backlighting level for optimum viewing. And will even reverse
the display from black-on-yellow to yellow-on-black for
nighttime viewing.
See your GARMIN dealer to feast your eyes on the new
standard in panel mount GPS maps. With or without the
built-in Comm, you’ll see satellite mapping technology in a
whole new light.
