"We've all been there, or know someone who has. There's an accident and no witnesses, it is just your word against theirs. The police report will say it’s a no fault and YOUR insurance will go up. Or worse, your car is totaled and you may get nothing from your insurance. That is the moment you'll wish you had a black box for your car. Well here it is, this new top of the line car cam not only records audio and video from both front and rear* windows but it also records much more information to prove your case. With its internal GPS system linked with Google® maps you can see the exact route your car took. The included RoadEye software will show your video footage alongside the Google® map of your trip featuring both your bearing and a speedometer. If an airplane can have a black box, why can't your car?"
