That's how effective Neil is. Notice, when I perform a wipe of non-volatile memory:
The wallpaper disappears.
The configured vehicle also returns to factory settings.
The option not to manipulate the User Interface also returns to factory settings.
But the saved places, even though I have deleted them from the (saved places) option, when I do a wipe of the non-volatile memory, they reappear. THEY NEVER BE DELETED.

In principle, I think that the traffic trend that appears in My Maps does not generate any problems in operation, just as you and Garman say.

Neil, I did what you told me and it works fine. I think that by deleting the GarminDevice.xml file and restarting it, when I connected to GE, that's when it gave me a complete update of everything I needed. I explained it in post 33, remember?

Anyway, I deleted it again and indeed as soon as I reboot, a new GarminDevice.xml file is generated. Look at the image, the files that start with MM are those from previous times.

I have compared the file it generates and the one I previously renamed starting with MM and they are identical.

Nobody ever seemed to use it much to listen to audio books on Garmin devices anyway in my experience but if you want the original files here's the zipped folder: [Only registered and activated users can see links. ]

Thanks Neil for the file, now I have been able to check how the Audiobook app works.

Thanks for your explanation, I'm more calmer.

One question: What video files can I watch in the video player? I have uploaded a .mp4 video file and the video viewer app detects it, but tells me that it cannot be played.
