Dear MaciejMajewski
The total mileage can be seen in the Unit Settings - Common tab (there you need to configure the initial mileage and it will be automatically summed up with the mileage that will be calculated by the application from the moment the unit is connected to our platform).
There is currently no option to display the total mileage on a unit card.
Thank you for your question, we will discuss introducing such a function and possibly implement it.
