Care Information
Cleaning the Unit
Your MX20 has a durable display, but reasonable
care must be taken to maintain its performance and
life. To remove stains, smudges, fingerprints, and
so forth, we recommend these cleaning methods.
If the first method fails to remove the problem, try
the next method.
• Wipe with a clean, dry, non-abrasive fabric
(for example, cotton or handi-wipes). Do
NOT use paper products, such as paper
towels or facial tissues.
• Blow on the area to condense moisture on
the display and then wipe the area with the
clean fabric.
• Moisten a clean fabric with a small amount
of water and wipe the display area.
• Apply a small amount of glass cleaner
(without ammonia) to the fabric and wipe
the area.
• Apply a small amount of isopropyl alcohol
and wipe the area (this is your last resort).
To resolve problems that cannot be remedied
using this guide, contact Garmin Product Support
in the U.S.A. at 800/800.1020 or Garmin Europe at
44/1794.519944.
Display Backlight
The display backlight is rated by the manufacturer
as having a usable life of 20,000 hours. This life
may be more or less than the rated time depending
on the operating conditions of the MX20. Over
time, the backlight will dim and the display will
not perform as well in direct sunlight conditions.
The user must determine by observation when the
display brightness is not suitable for its intended
use. Contact Garmin AT repair station or factory
authorized repair station when the backlight
requires service.
