In my search for the Integra RDC I just found one retailer that assures me that he has 2 units witht the pre-installed upgrade (which has not yet been officially released). Integra told me that there are few units in the streets with the pre-installed upgrade. The problem is that they can't confirm by serial number if the unit has the upgrade. The unit was manufactured in March 2002. Do you think is possible that it really does have the pre-installed upgrade? How can I be sure?
