Hi glassjoe,
Nice install that has me thinking about this Android version instead of the older WinCE D5166XU for a little less.
Quick question about your sub connection. I see that the Android GA6166X has only ONE sub output RCA line and I'm currently running a mono block amp that takes a left and right channel and mixes it. Connector #10 in the below picture:
How did you configure your sub amp input connections?
PS: I also don't seem to see a reverse sensing wire in their diagrams for the rear camera
Thanks,
Mike
