When your vehicle is not receiving signals
from the satellites, the “GPS” mark does
not appear at the screen.
The GPS signal may be physically ob-
structed, leading to inaccurate vehicle
position on the map display. Tunnels, tall
buildings, trucks, or even the placement of
objects on the instrument panel may ob-
struct the GPS signals.
The installation of window tinting may also
obstruct the GPS signals. Most window
tinting contains some metallic content that
will interfere with GPS signal reception.
We recommend not to use the window
tinting on vehicles equipped with naviga-
tion systems.The GPS satellites may not send signals
due to repairs or improvements being
made to them.
Even when the navigation system is re-
ceiving good GPS signals, the vehicle
position may not be shown accurately or
inappropriate route guidance may occur in
some cases.
