Add-on Electrical Equipment
The OnStar system is integrated into
the electrical architecture of the

Software updates or changes may
affect or erase data or settings that
are stored in the vehicle, such as
saved navigation destinations or
pre-set radio stations. Neither OnStar
nor GM is responsible for any affected
or erased data or settings. These
updates or changes may also collect personal information. Such collection
is described in the OnStar privacy
statement or separately disclosed at
the time of installation. These updates
or changes may also cause a system to
automatically communicate with GM
servers to collect information about
vehicle system status, identify
whether updates or changes are
available, or deliver updates or
changes. An active OnStar agreement
constitutes consent to these software
updates or changes and agreement
that either OnStar or GM may
remotely deliver them to the vehicle.Privacy
