OnStar FMV Mirror - Types of Mounts

Types
of
mounts ...
Below
are
the
three
types
of
mounts
you
will
see
once
the
OEM
mirror
is
removed,
as
well
as
the
adaptor
that
may
be
necessary in
order
to
proceed
with
installation.
BIGFOOT
MOUNT
An
adaptor
IS
NOT
required.
SMALLFOOT
MOUNT
An
adaptor
IS
required.
CAM
LOCK
MOUNT
An adaptor
IS
required.
Because
it
has
enough
surface area
to
support
the
weight,
the
OnStar
FMV
Mirror
can
simply
be
slid
onto
this
mount.
Because
of
its
limited
surface
area, a
smallfoot
mount
adaptor
IS
required
before
installing
the
OnStar
FMV
Mirror.
Because
of
its
unique
shape, a
cam
lock
mount
adaptor
IS
required
before
installing
the
OnStar
FMV
Mirror.
