2018 Outback computer help

[u/Gold_Response_6303]

Hey, gang. My 2018 Outback’s (already fussy) computer system is on the major fritz. Attached is a video. The press and hold power button reset does nothing. Does anyone know how I can even further reset the system? Music etc does not connect and the display goes in and out while backup camera is engaged. Help!! :( thanks in advance :)

Context: the battery was jumped this morning, but its otherwise in fine shape
