Handsfree locked
 

I’ve just bought a 2018 Mazda 2 skyactiv and when I try to use handsfree to make a call it keeps saying “handsfree locked please input passcode’ I don’t know passcode as obviously I’ve just bought car second hand. Can anyone tell me how to reset or delete code please. I’ve connected using Bluetooth and can receive calls I just can’t make calls handsfree.I’ve seen comments about resetting but my radio is different to the ones mentioned
