I just came across the Xtrons PSD70IBS while trying to get an latest Android 10 Car Stereo to upgrade my Seat Cupra 2010. To my surprise, it still has the DVD player. I am wondering is it still necessary to get a car head unit with DVD player? I hear from my friend that dvd is outdated. Why they still have this feature? Isn't that we can listen to music via the Android apps like Spotify?
