Actually no, sorry - you just lost $5... I started the upgrade process then exited the car, shut the door, and went back in the house to post here and check network traffic.
I remember once having an issue with an update because I got in the car before it was done, and the update failed. Had to go in to the service center to get them to push the update again. Definitely don't want a repeat of that mess for 7.0!
