If you need an independent witness when driving, you need a dash cam. Garmin's Dash Cam 55 Plus can also record when you're parked, will warn you of speed cameras and can even be controlled by your voice.

I did I loan of research when purchasing this Dash Cam, great little device with a very neat windscreen bracket. It has a load of extra features like speed camera locations and land avoidance which is a added bonus, as always great service from John Lewis as always Thank You.

Wide angle 120 degree not nearly good enough this really need to be a wide angle 170 degree plus, which is now available, not as discrete as I hoped it got a brass ring which means its even less discreet, its a bit fiddly trying to place the self-adhesive magnet on the windscreen as you only get one...

Great little camera, small, light and discreet. Does what it says and records good quality pics. Will turn on and off with the engine. If you want to record while parked you got to get another power cable connected to an on/off current and an always on current and set Parking Mode.
