We used to have a built-in solution in our old car but being able to remove the tablets as well as the price makes this a no brainer for us. I just got 256gb micro sd cards and I can swap out movies (holds around 40 movies encoded in mp4 format). They use plex to play movies and after you enable google play store on the tablet you can download almost any app. The following is what we use, kids have been very happy!Sure, I don't mind a tablet based solution, but I was curious if anyone has a found a certain set of products (media servers, apps, headrest attachments) that work well? Was hoping not to try to figure this all out myself![]()
