Black Uconnect screen

2015 Dodge Dart GT. This might be a little long. Auxiliary battery has been on its way out for a while. The other day when I tried jumping it, the car started but had little power flow and finally died after about 2 minutes. Found 3 cells to be dead. Screen was working beforehand then went out and stayed out (guessing inconsistent voltages to have damaged the screen) Replaced battery, car runs good now but still have a dead screen. All fuses are good. Phone connects to system and phone calls have audio (cannot adjust volume), does not play music. Can still turn on/off blower motor, not sure if temp adjustment is working. Didn't fiddle long enough since I don't use it. I disconnected the battery and used jumper cables to connect the terminals and drain all residual power from systems. Let sit for about 20-30 minutes. Screen still does not come on.

Tldr; . do i just get screen from LKQ for a direct replacement(I found a verified functioning one). . Buy aftermarket android auto screen, my concern here is loss of heated seat/steering wheel function, A/C adjustment, and audio balancing function, shit, everything the original screen managed. . Im overlooking a more serious electrical issue. Such as BCM Thanks for the help! was definitely a long story.
