High definition dash camera to record video of your journey. I use this in a clasic car with sound on and it makes great video clips to post to the car club website for enthusiats. Its also a great defensive tool to show what hapened in the case of accidents or just recording the usual nutters on our roads. Records road speed, date and time as well as the g-forces when braking or accelerating - so if you are involved in an accident you can show what was happening. Download and playback on your laptop/pc etc. Excellent piece of kit.
