I forgot to mention...
If there's nothing in the wiring harness on the new Android radio plug for pin 17, then you do need to add a jumper wire from this (17 in the Android harness) to the factory amp trigger wire (21 on the factory wire) as shown in the second pic. Then make sure the wire is connected all the way through the various Android wiring harnesses.
If you guys think it will help, I can pull my head unit out this weekend and take some more pics of my wiring.
