I bought the F800 previously. Great video quality, but this is probably the most annoying product I've ever bought. Each time you turn on the car the damn device says "Recording started" "GPS Connected" "On your smartphone, connect to a WIFI hotspot that starts with Thinkware" in the most annoying voice you can imagine. I had to disable audio for it to stop, but this also disables most of the features on the devices, such as warnings and what not. FYI if you're planning on purchasing this.
