We have some good news!
The P2 Litecam is available now! This device allows you to add a reversing camera to your P2 (S60,V70,S80 and XC90) RTI screen.
The next step will be to implement this feature on a P1(S40,V50,C30).
As for the P3 chassis you can use CarPlay/Android Auto set to enable the camera in your Sensus system.
