I found an older Nuvi 755 in a Recycle bin. I determined that it needed a new battery which was an inexpensive easy fix.
The Nuvi worked great after the fix, including the Language Guide which I also installed. It was working for about a week until I did an update via Webupdater.
The firmware version 4.5 was up to date and not updated. There were a number of different language/voice files that needed to be updated also some font files and locales.xml files and device.xml files.
The update appeared to go fine with no errors. I was surprised that there were 70 files downloaded and updated. This got me worried.
On reboot the Nuvi appears to work except the Language Guide will no longer speak the phrase when you push the speaker icon. This worked before the update.
Other audio navigation directions from the Nuvi work. I tried reinstalling the Language Guide but same problem.
Fortunately I also made a backup copy of the complete Garmin directory before the update.
Is it simply a matter of deleting all files in the Nuvi Garmin directory and recopying all the backup files to restore it to what it was before the update?
Thank you for any information.
