Personal Note: Surprisingly this remote has proved useful for passengers in the rear seats.
As a driver you can be distracted by passengers requesting a change to the radio station or MP3 tracks, even though this can be done from the steering wheel, it can still be a distraction. However, by allowing your passengers to use the remote responsibly, they can leave you to keep your eyes on the road allowing for a safer journey.
