Purchasing autopilot after delivery

[Falkirk]

If you didn't pay for autopilot at the time you ordered the Model 3, is there an option on a screen to do so in the car? How does it get charged, to the credit card on file?

Thanks

You should be able to go to your Tesla account page and purchase online to charge your CC.
The price for the Model 3 AP upgrade after purchase is $6K ... ignore the Model S $3K for AP1.
