Recently I managed to install and set up the K2 system on my motorbike. Everything seems to work; after my first trip I checked the SD-card on my computer and the video's on this card cover my whole trip. Nice. But when I checked the same video's using the app on my cellphone (selecting "Document" knob) and then selecting the "Files in Device" knob this file seems to be completely empty!! Did I miss a setting somewhere? What went wrong?
