Part IV — Helpful Information: Appendices, Maintenance and service
Very little maintenance is required to keep this NAV ONE system in good operating condition.
Keep the unit components clean by wiping with a soft cloth slightly moistened with lens cleaner or isopropyl alcohol.
Do not use solvents or harsh or abrasive cleaners, which could damage the case or scratch the LCD.
Protect the unit from moisture and from being dropped or struck by hard objects to prevent damage.
Do not apply pressure to the LCD screen.
Consult the Cobra web site (www.cobra.com) for the latest software and database versions and compare them to
those stored in your unit to determine if updating is needed. Software and information updates are also available
in DVD ROM format and can be purchased as accessories. NAV ONE needs to be connected to a computer running
a Windows 98 or higher operating system with a DVD drive using a USB-2.0 cable to install the updates.
