You need to completely remove the power from the unit for a full power cycle.
I’d recommend removing the correct fuse then replace it, if you have tried a soft reset then this would be my next step.

Agree with the above either pull the fuse or disconnect battery for 20 mins

I’d also make sure the key isn’t inside the car when you disconnect the battery, sounds obvious but not worth the risk.

Also always disconnect the negative side of the battery only (the black lead).
