Buick Rainier Forum : “I have navigation in my rainier, but the disk is missing...where can I score one...”

If you want to pay a lot you could go to the dealership for the dvd. Otherwise you could check ebay or even some junkyards. Sounds a little crazy, but I am sure there are some junkyards out there that have a rainier with a dvd in the back.

junkyarddog.com is a good place to check.
