I think I have installed same unit on my antara 2014 diesel diamond. The one I did is from A-Sure. Probably the same 2/32gb.
Mine works just fine really. I added another screenview with Car Launcher. And all OK.
Did you maybe add an OBD (2) bluetooth scanner to it? I know I did to see the meters on the screen etc. All nice, but the 1st one I added drained my battery cause it never stopped scanning. I changed it for another one that automatically turns off after 30 mins or so. And havent had any problems afterwards. Also installed "torque prof". See pic with meters.
I had some issues with the a-sure system when diwnloading from the playstore. Some app blocking. But could solve that issue also. A-sure people are great help also. All my emails got answered same or next day.😎 though this last issue i had to find myself... their user manual is quite incomplete...
Hope it helps you out.
