IMPORTANT MAPPING INFORMATION – PLEASE READ
While the majority of turn instructions the GNAV20 gives you are correct, there are instances where a
city will post a “no U-turn” or “no right turn” sign after we release the map data. There are even
cases where a two-way street is turned into a one-way street, or a ramp or street entrance is
permanently closed.
While we strive to make the map data and turn instructions extremely accurate, we cannot guarantee
that all turn instructions will be legal, or even possible. Please exercise good judgment and caution,
and pay attention to all street signs and traffic regulations.
Do not follow the instructions of the GNAV20 if it suggests making an illegal turn or maneuver.
TIP
The system is equipped with Automatic
Volume Control. This feature
automatically increases the speaker
volume whenever the vehicle is
traveling at speeds greater than
50 MPH.
