How do I know which car parks I can pay using AutoPay?

In the app, AutoPay only car parks will show as Autopay on the map. P&D car parks which feature AutoPay as a payment method will show 'Autopay location' when you select them on the map. A messaging stating “AutoPay enabled” will show in the summary tab at the bottom of the screen. When you go to pay for a P&D car park you'll see a list of your Autopay enabled vehicles in the app, with the option of managing these.
