Can anyone identify this Android Head Unit? I am trying to find out if I can install 5.1.1 on it. It currently has has 4.4.4. The model number is AC8317. Kernal version: 3.4.35 root@ubuntu #51 Thu Apr 28 10:41:26 CST 2016. I am not to familiar with android because I always had apple devices but I got tired of them. I am trying to learn how to customize these. The home screen widget cannot be moved or deleted. It is stuck in KPH and 24h time and wont change even thought I changed the setting under car settings. It has 1gb of ddr3 and a 1.6ghz quad core A9 processor and 16gb Nand, not sd card slot.
