Thanks for the explanation, I understand everything now. I did not know that in Japan there are different road signs. I never paid too much attention to the indication of road signs and considered this function as a toy. It was showed main Ukrainian road signs (like speed limit), now I will pay more attention at this toy. As for navigation in the car radio - I generally turned off the display of maps and voice prompts, because in Ukraine it does not work, there are Japanese maps only . I was even going to buy a Chinese car radio, but it was a pity to remove Gathers, because there is a quality audio and I did some changes - for example, I used the button on the turn switch to display a picture from the rear camera. (As I wrote, my car was redesigned from the right-hand car, a donor car from the USA was used and there was a button to turn on the side camera on the right mirror.) Generally, I want to equip the car by 4 cameras in the future.
My car was firstly bought in Nagano, I even looked in Google in which car dealership. And 4WD Fit I wanted, because it has better ground clearance (150 mm vs. 135). In the end, 4WD performed very well last winter here, I'm very happy with it. May be there is only one question - this car model (Mk3 2015 - 2020) has never been sold in Ukraine, it is rare here, so there may be problems with spare parts in the future. But I hope everything will be fine. Sorry for off topic.
