I have been given a Hero3 and found it difficult to take when driving in terrain hands off the wheel to operate the camera. Therefore - and because I have probably not researched enough - I ordered this set. As I said, for the Hero3 one needs the WiFi BacPac not, since they already have WiFi on board. The problem addressed here many times with the necessary updates I had, it was very tedious. The camera can upgrade directly to the home page for the WiFi BacPac and Remote Control must be the software "GoPro Studio 2.0" download from GoPro website. This is actually to edit the recorded movies, but includes a module for firmware update of all GoPro products connected via USB. After these initial difficulties, I have the camera now regularly in use, the interaction with the remote control is going great, when you get used to the slight delay in the operation of the camera (it will take a tiny moment, to the control input via the remote control at the camera effect shows). In my view, the remote condition is a must for the use of the camera while cycling, but due to the complicated and time-consuming update functionality, there are only 4 stars.
