Jabra c330 User Manual

PPENDIX

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 c330. To purchase, go the Garmin Web site at  

 and select the 

“Accessories” link. 

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 c330’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.

Garmin periodically updates its maps so that you can enjoy the 

most accurate route information. If you registered your unit, you 

will receive notification of map updates. Otherwise, check the 

Garmin Web site at 

 to 

see if an update for your map software is available. 
See 

, Customizing the Map Page, for instructions on how 

to find your current MapSource software and version number.

In the rare event you sense that the touchscreen is not responding 

properly to touch commands, calibrate it by pressing and holding 

down the Power button until the Calibration screen appears. 

Follow the on-screen instructions.
