If your windows are tinted, ensure that you use non-metal tinting instead
of metal oxide tinting. Both of these factors can interrupt GPS reception.

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.
