The navigation system utilizes a database stored in a special format on a
DVD. It is recommended always to use the latest update of this map
DVD.
• The navigation system will only work with DVDs specifically intended
for your navigation system.
• Always store the map DVDs in their protective cases when not in use.
Ordering additional map DVDs
If you wish to order a replacement or additional map, please call

Latest map DVDs
The map content is constantly changing due to new roads, traffic
restrictions, etc. . Therefore, it is not always possible to exactly match
the DVD map with the current roadways. For best results, always use the
latest version of the map DVD. Map information is regularly updated, but
all areas are not necessarily covered to the same level of detail. Some
areas, in particular private roads, may not be included on the database.
To help with accuracy, always use the latest DVD version for navigation.

RADIO FREQUENCIES
AM and FM frequencies are established by the Federal Communications
Commission (FCC) and the Canadian Radio and Telecommunications
Commission (CRTC). Those frequencies are:
AM - 530, 540–1700, 1710 kHz
FM- 87.7, 87.9–107.7, 107.9 MHz
RADIO RECEPTION FACTORS
There are three factors that can affect radio reception:
• Distance/strength: The further you travel from an FM station, the
weaker the signal and the weaker the reception.
• Terrain: Hills, mountains, tall buildings, power lines, electric fences,
traffic lights and thunderstorms can interfere with your reception.
• Station overload: When you pass a broadcast tower, a stronger signal
may overtake a weaker one and play while the weak station frequency
is displayed.
