Apple App purchases neither have nor need a product code.
To activate your license purchased within Sygic app via Apple App:
- Open Sygic GPS Truck & Caravan Navigation.
- Go to Menu -> Sygic Store -> Restore.
- Click on the Restore button and type in your Apple ID and password when requested.
- You can check the activation by going to Menu -> Sygic Store -> All your licenses - if the product or service is listed there, then it has been successfully activated.
The restore will fail if you change your Apple ID or use a different Apple ID than was used to complete the in-app purchase.

Please note:
The Sygic GPS Truck & Caravan Navigation license may be activated on only one device at a time. Should you transfer the license to a new device, it will be automatically deactivated on the previous device.
The license purchased via the iOS app is not possible to transfer between platforms. You can use it only on iOS devices.
