Note: To avoid risk of injury from a deploying airbag, never place a child age 12 or under in a front seating position without a dealer installed airbag deactivation device.
Comes with deactivation unit that must be installed by an authorized Porsche Dealer.
Now the next question... will the Durametric software set up the computer for the deactivation bar or will I need a PSTII?
