I plan to keep my car for years, so I think it was worth the investment. I now have phone mirroring, rear DVD player, Roku player and front camera installed. I use the rear DVD player the most just to see what my kids are watching. I've had zero problems after they fixed my dead unit. I still don't like that my unit was NOT 100% plug and play nor does it do Android Auto, but it's OK.
@Simi_MDX. I was referring to the Navtool Carplay/Android Auto for the Center stack display, Are you referring to the same or the DVD unit for Rear seats?
