You go to the Chinese website you bought it from and scroll up and down until the cute girl assistant in the box asks you what she can help you with. you type in that you would like a skilled engineer that speaks your language to attach to your Maxi Sys and set up the coding on the BMW while she does a web cam dance for you while the Engineer is entering the coding to the.vehicle.   Then you wake up and go to work and spend your lunch time emailing and calling for support in China for the next 2 weeks:-)
