"The most expensive paper weight I have ever purchased. What absolute piece of rubbish. Once autocardvdgps get your money they completely ignore any further correspondence. I had the unit installed for 24 hours before i ripped it out. Nothing functions on the head unit a advertised. Unit takes 2 minutes to start up, steering wheel controls seldom work. Selecting iPod songs are a mammoth task with slow scrolling, unit does not come with any maps, dvd player displays a constant screen do play whilst driving even with the engine off. Head units are manufactured by Witson S100, who also take no responsibility for the faulty units. Anyone trying to contact autocardvdgps can email them on ****@****. Good luck."
