Introduction
Why? Because I now have a fully functional Android based head unit, with NO limitations. Full Android Play Store, and 100% android and google support.
This definitely was not easy and took a lot of trial and error to get this nailed down. Some of the biggest struggles were finding a DAC capable to output the required power to power 4 speakers, where I ended up having to use a 3rd party amplifier. I was also concerned about how I would power down and power up the PI without damaging the SD Card, however this build of LineageOS for the PI uses a read-only filesystem which means you can just power it on and off as many times as you like, in any state, and no damage will occur, this solved a big problem, and possibly the one and only problem that was make or break for this entire project, was no longer an issue.
