It reassures me, I was wondering if I wasn't starting to lose my mind

when you tried the one in message #3561, you must not have taken the precaution of restarting the navigation with a truck as your vehicle.

If the program is only put to sleep and continues to run in the background the switching of the filtering cannot be done. It is a static filter set up at start-up and the change of vehicle during operation does not allow the switchover, you really have to restart the program for it to work correctly with this minimum modification.

adding a shortcut button is quite doable but it would require going much further in programming with means more substantial than a few lines of code which can quickly become a headache.

Due to a singular demand for occasional use, keeping it simple despite the operating constraint was an acceptable solution.
