route mic to a different connected Bluetooth device

[backslashV]

Hello,
My car has it own Bluetooth system but to be able to control media I had to purchase the Kinivio Bluetooth system which has a built in mic. The problem is that its quality is not as good as car's mic. How can I force the phone to use car's mic for calls? Any tasker magic?

Thanks

Not even Tasker. You can only have one phone or one media source at a time.

Actually I have both bluetooth systems connected at the same time.
