Started this project late summer 2019 with some inspiration from the Pioneer SBH-10BT These were rare as hens teeth at the time. Also looked at making a tablet / phone combo head unit. Came across open auto from various youtube users and started in there. This project evolved from a pi3b that I already had to the newer pi4b 4gb model. Currently using the 7.0 version of OAP with a samsung galaxy S7. Below is the parts list some of which you may not want or need but these all work together with very stock settings. I did retain my old Sony headunit for cd/am,fm and a usb , front aux utility it has a decent amplifier and the rotary volume control for safety. it does have an IR remote (not much help).

The performance of the project is just what I needed for a Daily Driver. Versatile and much safer as I learn to use the google assistant and the handsfree phone controls of Android auto. Finally used a composite camera with a usb capture card works well so far. Thanks to Skrimo for the great work on the shutdown timer. Followed your instructions to the letter using slightly different relays but same principle. Opted to use two power supplies one for the pi and its associated usb dongles, the other for the screen and the usb hub power.
