First thought it's the blue tooth interference or the fuse in the trunk, it was not. Turned out to be the faulty BT module. Bought a new module from local dealer (no warranty coverage because I bought MPE from oversea) and problem fixed.
How much did that cost you?
Equal to about 400-450 USD but keep in mind auto part price in my market hugely inflate like the car.

I was also told bmw normally doesn't sell module separately and there's no part # for it.
