The new 3-Series currently supports all Huawei mobile phones to generate electronic keys, that is, if you have Huawei mobile phones, you don’t need to take car keys when you go out, and the mobile phones can be unlocked remotely.
Apple’s mobile phone is not working yet.
The agreement is under negotiation.
It will be supported soon.
