I currently have a K2. I spent a LOT of time getting the cameras, GPS, and power routed through the frame channels. I am proud of the installation. My wife has mentioned getting a camera for her bike, but she doesn't ride nearly as much as I do. My thought is to purchase the K3 for me, and move the K2 to her bike. My question, can I simply swap the K2 controller/recorder with the K3? I would leave the existing lenses on my bike, use the lenses with the K3 on the K2 controller/recorder for her bike.
This would allow me to have audio on my all rides. When we ride together, I would use a wireless/remote microphone so she and I could talk while still having it recorded.
