Handling and Care of the Disc
Some basic precautions are necessary when handling your discs.
Discs you can use
• Use only the disc provided for use with this unit. You cannot use ordinary DVDs, CD-ROMs, or music
CDs.
• Do not try to use a disc that is cracked, scratched or bent.
• This product is designed for use with conventional, fully circular discs only. Use of shaped discs is not
recommended for this product.
Precautions for handling
• Do not touch the playing surface of a disc. Hold the disc carefully by its outer edge or by the hole in
the centre.
• Do not attach sticky tape or suchlike to the surfaces of a disc. Avoid scratching the disc, or damaging it
in any way.
About cleaning
• Keep your disc clean and free of dust. If you need to clean a disc, use a soft, lint-free cloth to wipe the
surface from the centre outward, as shown.
• Never apply solvents to your disc, such as benzene, thinner, commercial cleaners, or anti-static fluids
intended for vinyl records.
Precautions for storage
• Keep your disc away from direct sunlight, sources of heat, and sources of dust. Store the disc in its
protective case to provide greater protection against warping.
Ambient conditions for playing disc
Ambient conditions can affect the behaviour of discs and the operation of the system.
• Vibrations caused by driving may sometimes interrupt the reading of data from the disc, causing slow
screen changes.
• In cold weather, condensation may form on the optical lens used to read the disc or on the disc itself,
particularly when the vehicle initially warms up. This may render the disc unreadable for up to an hour
as the moisture evaporates naturally. You may wipe condensation of a disc with a soft cloth (from the
centre outward).
• At extremely high temperatures, a temperature cutout protects the Navigation System by switching it
off automatically.
• Despite our careful design of the product, as a result of mechanical wear, ambient conditions for use,
or handling of the disc, small scratches that do not affect actual operation may appear on the disc sur-
face. This is not a sign of the malfunction of the unit. Consider it to be normal wear and tear.
