Marco, I forgot to answer your question from before, yes there's no remote control, but it's really easy to operate even from a bad angle.
One more thing is, I have to clean the lens off, when offroad riding, if I don't do so I get a blurry picture, but that's pretty normal. I didn't pay attention to this while riding.
Next time I will try the sidemount for the helmet, it's another angle that looks promising.
