Ordering Map DVDs
You will receive two free DVD map disc updates
with the purchase of your new vehicle. Updates
are necessary to make sure that your vehicle’s
navigation system has the most accurate
information available about streets/roads, points of
interest, and business locations.
The updates are provided by the GM Nav Disc
Center at the first and second anniversary dates of
your vehicle’s delivery date. About four to
six weeks before those anniversary dates, you will
receive a post card from the GM Nav Disc
Center reminding you that a free update is
available. The center will request confirmation of
your mailing address either by having you
contact the toll-free number, 1-877-NAV-DISC
(1-877-628-3472), or the center’s website,
www.gmnavdisc.com. After verifying your address
you should receive the updated disc in about
two weeks. After receiving the updated disc,
replace the old disc in the navigation system. See
“Installing the DVD Map Disc” and “Ejecting the
DVD Map Disc” under Maps on page 30. Dispose
of the old disc to avoid confusion about which
disc is the most currect.
