On pc - when using ANY Moza wheel rim, the joysticks on any Moza wheel rim cannot be used to navigate menus. This has been an issue since launch. The joysticks can not be binded in settings either for use for menu navigation.
This affects any wheel rim + base combo including r3 which is on compatible list on pc.
This list includes all current Moza rims such as CS, RS, FSR, KS and ESX / XS rims as well as all other wheel rims by Moza racing.
This means it’s a requirement to use additional input method such as Keyboard + mouse for menu navigation or controller.
However joysticks can be mapped for navigation on Forza Horizon 5
