The speed reminder does not switch to a new setting when km/h is changed to mph thus if you set 110 km/h for the reminder then decided to display in mph the reminder would not alarm until you reached 110 mph. Thus invoking "Daddy why is everyone going so slow" " license and registration please, hands on the steering wheel and step out of the car please"
Otherwise works great
