I recently completed a survey which asked if I had any ideas for future products perhaps related to the 50S I just acquired (I've actually purchased two...one for me and one for my wife). At that time, I went blank and had no suggestions. However, since that time I had something come to mind.
My wife and I have taken an occasional vacation where I ride one of my bikes and she drives her car. She doesn't mind going on short rides once we get somewhere, but she has no interest in a long day on the bike. But on the way to a destination, it would be advantageous to us for her to be able to click her 50S into some sort of headset while driving the car to communicate with me on the bike. I visualize it as being similar to a lightweight set of headphones.
