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.
