Mercedes Speakers/MIC
If i am talking with someone by using Bluetooth connection (using speakers and mic from mercedes), the people are saying to me that person who is talking from driver seat has very low sound and sometimes they hear every second word .... but on seat next to driver seat, they hear it very good.
I am not sure if there is something wrong with driver MIC or maybe i just need to setup something... does anyone has any idea what can be wrong and what can i do?

I had the same problem on my own W213 after HU55 Comand Update from Xentry Online with 07 2019 Regio DVD's.
After Online SW Update, the variant codings are recorded wrong to my HU55 device's Handsfree Parameter from Daimler Server and the microphones are sucks.
After update and SCN Coding , Low sound is going over phone to other side + On the conversation other side can not hear your words as clear.
The solution is very easy;
Connect to HU55 over Vediamo or Monaco
then Go to Hands Free Parameter 4092
Change the Default or W213 parameter to 205
Then Save coding and make hard reset
Done.
Sound is going to other side in high volume and clear. No need to change MIC
Good Luck
