Ive just had this problem this week. If you've not sorted it yet i will tell you what i did.
If you notice the bypass connector doesnt have a red live wire, this is the problem... There are 2 yellow wires within the bypass iso that connect together at the end in the block connector. Now if you look at the block connector from your stereo you will see you have the black/red/yellow you will see nothing goes to the red wire(live) i only come across this when i made a live wire to power up the stereo from my ignition.
What you need to do is split the yellow wires, one is a live and one is accessories. The one i used as a live (the red one) is the yellow wire that comes from the bottom of the conector grey wire on the main connector (if that makes sense).
