There is a problem with the system of the navigator. By touching a field, e.g. "Favourites", the background colour turns brown,
but nothing happens

I have learned to live with this so that touching is not too short, not too long and sometimes you have to touch several times.

Instead of sending you the device, waiting a few weeks without a device and getting it back with the same problem, I decided to live with the fact that I am using a poor quality device.
