Okay, here is the outcome.

The numbers should be different. The dealer said the card is wrong and they
need the NAV SN. They will have to pull the unit. I knew I saw the SN
somewhere in the programming screen. I asked can they get it another way?
No. I went to the car, pressed the three button sequence to get into the
programming of the NAV. I pulled the SN, they generated me the code. All
is well.

So, keep in mind that none of what I was asking is in the owners manual.
