Hello catymag.
Finally I will start all over again.
Regarding your last post, I had plenty of vpm files the voice folder, comparing your language options with mines is the same, and tue volumen was always 100% (by hand pushing the up button).
Finally I thougt to reinstall the language options. I removed the Street pilot language additional app and it took off also the main SP app. After a reinstallation of the apk, including both .so files, something happened, and I can not change permissions to libgarminos, and SP starts with the battery icon issue, there is no language options and there is no maps detected.
Strange, It was working fine besides the Español_Americas issue.
I´ll start all over again. I´ll try the one posted by baghdadvaio, the 2.22 version for my rooted I9070.
Thanks for your time.
Regards.
