Using The Mounting Bracket
To mount to dashboard, use the included adhesive disk.
Choose a clean, dry spot on your dashboard, peel off protection
liner from the back of the disk, and then attach the disk to your
dashboard.
4. Rotate the bracket adjuster to adjust the angle of the bracket so
that you can view the GPS unit display and operate the controls
safely.
Warning:
When you mount the device in your vehicle, ensure it has a clear line
of sight to the sky.
The device must not be mounted so that it impairs the driver's view
of the road. Please take extra precaution to ensure the airbags are
not obstructed by the device.
