Hi ,

I' m using navcore 9.026 and i'd like to test Navcore 9.058.568435.1 on my device .So ,what files i have to download and i need also a step by step tutorial .

Thanks in advance

If your Navcore works fine you should leave it as the X10 models can be quite tricky with new Navcores.
However if you need a newer Navcore to use the HNR features you would be best off with the automatic installers, but make a backup using Windows Exlorer and not Home first!
