I had a completely legal Mio gps TV device that for some reason lost all content after connecting to a computer
I also tried to legally recover the device, I was in correspondence with their support for almost 3 weeks
In the end, it ended with them asking me to pay 60 euros to restore my system (!!!)
Of course, I sent them the hell away, spent the next ten days trying to find what I needed and barely succeeded in it by combining various methods.
I got some content from others, recovered something over the full edition of mio desktop, I stole some from the Mio server (it was possible then). After that, I inserted a shell with IGO on the card and continued to use only it.
I sold it like that after a couple of months.
