[Android Head-Units] mlazambuja:
I'm trying to identify the MCU of my new head unit (it came with my Mitsubishi Outlander) and if it's a MTCB or MTCD.

I found out it's based in Adayo DN6V26, running Android 4.2.2 but I'm trying to figure out what's the correct MCU. It's sold by a local (Brazilian) company called Logigo. It has

I added attached pictures of the head unit and version numbers.

I already got root on the device and can boot in recovery mode.
