I have performed a reset. Today it locked up on me four times.
When plugging it in today to check for the folder, Windows told me there were errors on the drive that needed to be fixed. (I assume that is the majority of the problem now, but it didn't tell me there was a problem with it yesterday.) After telling it to scan and fix, it found some errors, corrected them, and placed some orphan files in two 'FOUND.000' and 'FOUND.001' folders. There are approximately 20 files in each folder, and each file is around 80k in size.
The LoquendoTTS folder is there, with correct capitalization. However it is only 1.4 gigs in size.
I have no backup to restore it to, and my discs that it came with are god knows where. I bought it three years ago, or there abouts.
The app version is 7.903 (9183/04301). The GPS is v1.21, the Boot is 1.0012, and my map is North_America v825.2158.
Additionally to my not being able to download computer voices and it freezing four times today, the battery does not seem to want to hold a charge any longer. After being left on the charge cradle last night, when I took it off this morning I got the red low battery notification right away. With it plugged in now and using the PC interface, it is showing that it is constantly charging and has done so for many hours now. I'll let it charge again overnight... perhaps a cable was kicked or not plugged in tightly last night (I have to really reach now to give the device the benefit of the doubt)
I realize that I may have a lost cause on my hands, especially with the battery issue, but I would like to make it better if possible. My TomTom has been very reliable up until these last few days.
