I don't actually know when it was implemented, but I do know that it is current as of January 2011. Not sure about being covered under CPO. I believe strictly speaking programming isn't covered under CPO, but if there is a problem with a component and that requires reprogramming then they might be willing to cover it under CPO. Have the dealer hook it up to the computer and ask them what the current integration level is (ISTA/P), you should be able to get a printout of it.
