Infotainment Hard boot

:
2019 CX5 Reserve AWD
Anybody know if this the correct hard reset for 16 CX-5?

Back + Nav + Mute

Had an issue today where the system was frozen, Back-up camera worked, settings and Nav worked but no radio or USB.
Shutting the car off then re-starting fixed it but I'd like to try the reset if it happens again in the future.
