My experience is that these clones are poor designed products, half cooked. Can't use bluetooth phone and GPS at the same time. the ipod interface is very poor. Volume control is another issue since each app has its own control. Glare is an issue. PiP banner is always displayed even if you don't want it. So don't expect a well designed, feature reach, supported product. As I said, it kind of works... half cooked...If I would've known all the issues, I wouldn't have bought it.
My two cents...
