My HU does not work with DASHCOMMAND
When asking the developer why Dashcommand does not work on my Joying HU this is the reply.

Check the devises app compatibility they do not allow our app to work with the head unit, this is why you can get is to work with your phone but not the vehicles head unit.

My unit is JY-SO002N3-JY-SO002N4GS

Other OMB2 app work!

And why does mine not work with this app?
