Your Navigation disc usually is in the CD player. Most require the First Disc to be the Navigation disc. Now if this disc was removed or if someone changed the position of #1 disc and inserted something else, then that is why you have your message.
It is also possible that removing the Battery from the car may cause it to lose the programming in the Navigation. It may simply need the Navigation disc to be reread.
The data on the DVD map disc ages at a rate of 15-20% per year. As the data ages, the functionality of the navigation system declines. Offering GM customers new navigation DVDs will ensure that the customers have the latest information for their system.
General Motors offered a Navigation Disc Update Program for alot model year vehicles. This program concluded on December 31, 2009. The DVD Navigation Update Program policy has changed and customers are no longer eligible for free annual updates, however, a navigation DVD update disc can be purchased for $199 (USD) + shipping.
If the navigation disc is needed for a warranty situation, the disc can be purchased for $120 (USD). The dealer must provide a VIN and RO# XXXXX qualify for the reduced price. The dealer must call the GM Navigation Disc Center, as this option is not available on the website.
The GM Navigation Disc Center launched on March 15, 2006. There are two ways to obtain an updated disc: * Via the web through gmnavdisc.com * GM Navigation Disc Center 1-877-628-3472
Technical Service Bulletins are sometimes generated to address specific
navigation radio operational or performance issues. When a navigation
radio bulletin is issued, it may contain instructions to utilize an
advanced vehicle navigation (AVN) software update with a specific part
number. GM dealers must order advanced vehicle navigation (AVN) software
update discs as directed in the specific bulletin.

Check for a scratched or dirty Navi DVD disc. Clean or have the scratches polish out at your local game store. Video game stores usually have a disc repair machine that polishes out scratches.
Note: In some cases the Navi unit can cause rotational scratches on the DVD. If this is the case than the Navi unit will have to be replaced.
NAV unit uses a DVD disc. If its a copy, it may or may not work. I suggest you remove the NAV disc, unplug the NAV unit from power for 4-5 minutes, reconnect the NAV and try inserting the disc again to see if it reads. If it still does not read, another NAV disc needs to be inserted to verify its not a "bad" NAV DVD disc issue. If it still cannot read the second disc, the NAV unit is bad. The handbook feature needs the disc inserted in the slot 1 of the CD changer unit.
I am just guessing, but it sounds like whoever traded the car in might have given you a disc that wasn't for your particular vehicle??? I ordered a disc online, thinking I had the right one... and it read Disc Error as well when inserted. However, when I got the part# right, the new disc worked like a charm.
Also, when I bought my Charger... the dealership told me that it is not uncommon for the former owner to switch out discs before they trade the car in. I would call your dealer and read the number off the disc to them... so that they can check it to be sure that it is one that should be compatible with your year/make/model before I went any further.
