Hello bigfatdeal and fongo, thaks for answering!

The radio is the original equipment that comes with the same car (a Volkswagen Gol Power) in the latest models. Mine is from 2007 and had an horrible only-cd system, so i bought the new one via the local eBay and replaced it.

The model is the "1-DIN Mid NLP" manufactured by FAMAR, an argentine company licensed by the international DELPHI. This model ships with many current VW cars to latin america and méxico, so it's pretty common around here. Is a very good, cheap, and complete system, I've found posts in a german VW forum trying to get info about it, as they were surprised by all the things it can do and the price, all of it coming from OEM equipment.

Here's the product page: http://www.famar.com.ar/prod-audio-1dinmid.htm

And the manual (spanish): http://www.famar.com.ar/servicios-manuales.php

It's known they used to send firmware upgrades via email that you can run in the radio via CD, but they doesn't seem to be responding to my email, as I've sent 3 so far

I've read about the same problem with the same phone and the same radio, and other radios also. I'm confused and I don't surely know if it's a problem from my phone or the radio

How do I search for the BT module info? I have to open it and see the circuits right? I can do it, warranty is not a problem, but is it worth the work?

Thank you SO MUCH for your help guys.

PD: I'm i little sad as three days ago a motorbike ran into my left side. Luckily the guy is fine but my precious has to go to the paint workshop
