Rear monitor

Hi all! I recently purchased a 2014 Dodge Grand Caravan SXT. After getting it home we realized that the previous owners switched out the OEM stereo with screen/dvd player for an OEM stereo without the screen so there was no dvd player or backup camera anymore. My husband replaced the stereo with an aftermarket one so we could do CarPlay as well as a new backup camera, but we still don’t have a DVD player. I was trying to figure out a way we can still utilize the rear monitor with our children, and am wondering if anyone else uses a streaming stick or what is needed? Also, there is that little compartment in the front where the Blu-ray player could go. Is it an option to add one if we purchase an OEM one?
