We have worked to integrate the OVMS device [https://www.openvehicles.com/ ] to provide the missing app functionality to the MGZSEV.
Currently it is possible to get a lot of data from the app but not yet to control any features. We are very optimistic it will be possible in the near future once we have captured some data from a Thai/Indian car which has the telematics unit working. If you can help us please get in touch.
