Sorry for sounding ignorant. What is "charla"? Yes , my address is in indeed in city of BA.
Charla means chat. You (along with everyone else who is renewing their license) must go to the comuna which has "jurisdiction" for your domicile and there is a one hour group meeting about driving (most weekdays at 7 PM). They give you a paper when you enter and you will write your name and DNI number on it.
After the charla (you shouldn't have to say anything...there were over 100 people at the charla I attended), the "leader" will sign all of the papers and call each person to give them theirs. This paper must be presented when applying for your license. I didn't understand everything that was said, but it was clear there was a strong emphasis on drunk driving and the high number of fatal accidents in Argentina. Basically, the prupose of the charla is to raise consciousness of those who are renewing their licenses but are not being retested.
As soon as you have your DNI go to the comuna and ask for an appointment for the charla as well as a turno to get your license.
By the way, I had no idea there was a charla (or even what it was) until I went to the comuna in Belgrano to ask about renewing my foreign license. They gave me the turno for the charla as well as the turno to get my Argentina license. It was all a complete waste of time as my foreign license was "rejected" at Roca.
A couple months later I applied for my Argentina DL after moving to Punta Alta. The accepted my expired but renewed by mail Illinois license (with an "unsigned" sticker on the back). I got the new DL without taking a written or driving exam or attending a charla.
I also had to provide the results of a blood test as my blood type had not been specified on my US license. They may do the blood test at Roca, but I'm not certain. I never got past the first (review documents) desk.
This thread (which I wouldn't consider "outdated") has more information about getting the license as well as the charla:
Driver's Licence......???
I found it using the search engine (key words: "charla" and "driver's license").
