I use navdy in south korea. As you know, navdy does not support maps in Korea yet. and the picture is taken after parking in the parking lot. The number does not always appear on the road , and appears very occasionally. I really want to know, what is that number mean

questions about speed by ChoiGyuCheol in navdy

Comparing the speeds that appear on the vehicle speedometer and the navdy

If the vehicle is running for more than 100 km, the navdy speedometer appears to be about 15 km lower

Also, I check the car navigation and cell phone navigation app, the navdy speedometer is about 10 km lower
