Problems Maintaining a GPS Fix
An optional external remote antenna (Garmin GA 27C) may
be needed when operating the unit in a vehicle with a coated
windshield or an in-screen heating system, which can block the
GPS signals. Connect the antenna to the connector located on the
back of the c320. To purchase, go the Garmin Web site at
http://www.garmin.com/products/sp320
"Accessories" link.
Battery Temperature Warning, Disposal
Your unit contains an internal lithium-ion battery, which allows
you to store more energy than standard batteries. All batteries
slowly lose the amount of energy they can hold over time. To
maximize battery life, limit your c320's prolonged exposure
to excessive heat and direct sunlight. Contact your local waste
disposal department for information on properly disposing of the
lithium-ion battery.
