Hi I’m having an issue. I have a 21 gc and I purchased and installed a 8.4 uav screen as mine was a 7 inch. Screen originally came on to unlock it with the code I got and then hours later no screen display. I read through the forum bought the mx+ obd and alfaobd on my android tablet but i can’t find a advanced mode to change it to the ram or Pacifica. When it asks vehicle I select one of them and when it connects it’s says my2020 not the ram or Pacifica I chose but I did go in and enable dcsd because it was disabled and turn the car off and when I try it it’s still blank but radio working. Am I missing something, so I need to do it on a windows laptop to get the right settings. Any help would be appreciated
