automatically switch to battery power.
Marine/Land Operation:
A universal mount is available for swivel mount installation in a boat or land
vehicle. Additionally, a Marine/RV Remote Antenna is available for installations
which require an external antenna for an unobstructed view of the sky. This
weather-proof antenna includes 30 feet of low-loss antenna cable. The
remote antenna has been constructed to thread onto a standard 1" antenna
mount. Antenna mounts, commonly used to attach VHF radio antennas and
Loran-C couplers, are readily available from your local marine accessories
dealer.
A Magnetic Mount Antenna is also available for attaching a remote antenna
to a metallic surface. This weather-proof antenna includes 10 feet of low-loss
antenna cable. A cigarette lighter adapter cable may be used to power the
unit in vehicle applications.
In addition to supplying power to the unit, the power/data cable allows you to
interface your GPS 55 AVD with other electronic devices such as graphical
displays or marine autopilots.
