I have a 2023 GX Prado auto 5-seater. I want to fit a genuine Toyota alloy bullbar myself. I understand the PCS radar in the grille, has to be recalibrated after being removed and replaced. However I need to go bush after the bullbar fitting, and before I can get the radar recalibrated by the dealership. Can the car be driven safely for a month or so, with the PCS radar inoperable?
