I'm backing it with the Home aplication.
I need only favorite places, Can I upgrade and then return favorite places to device?

Thank you

Make a backup using the Windows Explorer, Home won't cover all files you need.
The favourites are stored in your map folder - the file is [color="#006400"]mapsettings.cfg[/color]
In case you encounter a reboot problem when using your old favourites with the new map have look into out tutorials.

I need to update navcore and next update maps?
I do not know that last one is compatible with this device.
I looked at the pictures, it seems to me this version, NAVCORE 8.410.1218.
I have a GPS before updating the data completely erased?
Copy navcore to GPS and then map data?
What steps should I use to update?
