Replacing OEM bluetooth with Mobridge M2 Pro MOST
 

I retrofitted the OEM Bluetooth few years ago.
I'm thinking of replacing it to a Mobridge M2 PRO for the following reasons:

1. Phone quality - the main reason - on the OEM people always complain they don't hear me well or hear themselves ("twice"). The mobridge should work much better (?)

2. a2dp support - the OEM doesn't have the a2dp support.

What do you think? Can it work better or should I just add a parrot 9200?
