BMW OBD II Adapter

Hi guys,

I have the Torgue app on my phone and wanted to know if I can get a bluetooth OBD II adapter for my E90.

I am looking at these:

What I want to end up with is:

Phone mounted on my window. This is connected via bluetooth to my BMW.

Then I want to buy a Wireless music receiver and use the Aux jack:

Then I also want to use the OBD II adapter and connect that to the car and my phone.

Not sure if this will work and if my phone will handle 3 connections via bluetooth?
