Sadly no longer the case for 06's. Only the 07's are still eligible. GM wants (are you ready for this) $200USD plus shipping!!!! I only know this after calling the number and speaking with an agent.

We found the same thing...our Cadillac little suv had nav (summer anyway; screen dimmed in winter so you couldn't see it.) We investigated NAV upgrade, but ended up selling the vehicle before we bought the upgrade.
They gave us the same story.
