Well, I finally got time to fix my speaker/volume issue. Everything works great in that respect.
Unfortunately, the Axxess controller does not want to work.
I have triple checked all the wiring. Yes I connected the Grey/Pink with the Pink wire (pin 6) and the Grey/Blue with the Blue wire (pin 16). Yes, the ground, ACC, and Brown wire to the 3.5mm connector is going to the Blue/Yellow to me harness.
When I restart it and follow the series of LED flashes, it says that none of the connections are made and that it's identifying my HU as JVC instead of my Kenwood. Could this be the problem?
