No. The Ciclosport Navic 400 is a classic navigation device. The maps are pre-installed and the device autonomously finds the best route using the pre-installed software. GPS tracks and updates have to be transferred via USB & drag and drop. So to speak, a primitive, dedicated Komoot trouser bag. Considering how poorly Komoot works outside the major conurbations, this must not be a bad thing. There are interesting reviews of the Ciclosport Navic 400 on YouTube.

No. It can withstand rain, but moisture condenses in the display and makes it completely unreadable. Buy a more expensive device if you want to be happy with it.

Yes, everything is there !
