How do you exactly pull it out?

I have the same problem. I went to the dealer, gave them the VIN and registration and my DL and they said that they have to see the serial # of the headunit. So, I still don't have the code (I got the car used) since last month when I had to replace a dead battery.

I thought that registration and DL was all the dealer needed to give you the code. Ane help please!
