Like other navigation systems, the one present in your 2007 Cadillac Escalade requires updates to its software, maps and related information. An out-of-date navigation system won't show any new roads, highways or other new traveling information. General Motors releases an update disc for your Cadillac Escalade's navigation system yearly. You can order a copy of the disc by accessing the GM Nav Disc Center website or by calling the GM Nav Disc Center's customer service department.
