backnblack, the original poster (#1) was looking to unlock his Nav to input directions while driving... That's what the ebay guy was selling too, "Cadillac Escalade Nav Override Bypass unlock"...
We do not ned the $250 lockpick to do this, it is done basically for free this way:

both the lockpick and the above method involve removing the radio anyway, so why spend the $250!
I was looking for the nav unlock on the Escalade also, as I have done the above method on my H2...
