Thanks for the responses so far.

I went to a road test.

The MAP problem is solved after splitting the gmapsupp into the 3 original brazilian maps.

I updated also the "Brazilian raquel TTS" voice.

No good. The GPS still DOES NOT say the street name; just "turn right in 300 meters".

What I noticed is that (when selecting voices) some voices have a mark, in small letters, "says street names". The brazilian-raquel does not.

Has anyone gone thru this ?

Thanks !
