Hello everyone, I'm new here on the forum and have a question to ask. I have a TomTom XL 330S is imported it and I use it with map of Brazil, he has navcore v8.017 and I would like to upgrade. But first I would like to know if I can install any navcore for this model?

As said hundredts of time: A XL can be tricky, so it is a game of testing.
Apart from that it is no different than any other TT.

One more thing, if I change the navcore something wrong happens and the gps can stay forever unusable or have any way to recover the device?

Simply make a copy of your existing setup using Windows Explorer.
If something does not work out the way you want you put it back on an empty device and all is as it was now.
