Try to code it to hifi, that variant uses an external wired amp.

You can't do that.

If you want better sound than the basic stereo system, I'd recommend the Alpine hifi retrofit kit from BMW. It takes about a day fitting it since you need to pull a wiring harness from the HU to the car boot, an that requires removing a lot of interior trim parts, including seats and doorboards. But the result is absolutely worth it.
