It came with an external Microphone but they don’t allow you to use the OEM microphone wich was… honestly perfect. This is what the radio came with:

The microphone connects via 3.5mm Mini Jack. I tested it and I turned the microphone amplification to +10db because if i had it lower, NOBODY CAN HEAR ME. So… +10db, ok.
The audio quality in calls was so horrific that I thought… well maybe is this ****ty microphone, lets try another one. So I bought the Sony ECM-CS3:

I connected it with the same settings (remember, less than +10db means nobody can hear me), and… I still had the same Issue. The microphone audio is distorted as hell. I tested it by recording a call with my girlfriend. I’m the dude… and i can’t even understand myself. The worst part is in the middle, when I am driving in the highway (min. 8 aprox):

I though about trying to Isolate the microphone with foam because my actual setup is this:
It has foam underneath for vibrations, but the actual microphone has no foam around. I’ll test it later but for me it looks more like a software issue.
What do you think? Any idea of how to improve the sound quality? I found this post in a Tacoma forum where **a guy found a way to use the OEM microphone from Toyota in an Android Unit**. But I am scared of not being compatible with the Corollas:

Oh! I made a video (in Spanish, sorry. But **it has English subs!**) showing the whole setup of the radio where you can see everything better:
