HELP! Trying to hook up amp lead line to 20856087 stock nav unit
trying to hook up an amp lead line to 20856087 stock nav unit on my 2011. Pretty sure the speakers just splice into the 24pin unit that plugs into the back of the deck via the rear Low lines, but have no clue where I splice into for the power/lead/remote line from the amp (this is the line that connects to the amp that shuts it off when the radio is off, not the power line that connects directly to the battery from the amp). Help, please, my car is torn apart and this is the last Piece i need to figure out!

It's been years since I did mine but I believe I just tapped into a switched fuse at the fuse box for the amp turn-on lead. Wipers fuse maybe.
Edit: I still had the notes I took from the forum when I did mine and the trigger wire is the white wire at pin B3 of the main connector.
Either way will work.

All the amp talks about is a lead/remote line that needs to be connected from the amp to the stock stereo. I don't need power for the amp, that's already wired to the battery. Just need to find out how to hook up lead line.

I just told you! Position B3 of the main connector at the head unit. White wire is an amp trigger wire.

Was wondering if anyone has seen them carry any harness that plugs and plays to the back of a stock C6 unit (GM 20856087) that makes it easy to connect to a added amp & subwoofer system? I know they have one for the c5, but was wondering if there is something similar for the c6?
