Kenwood Wiring Matrix
I am in the middle of installing a Kenwood 9980 in my 2011 GS. I have the factory NAV which is being replaced by the Kenwood. I wanted to post a wiring matrix I put together for thoes experts who could help me if they see a problem with the way I am going to wire the Kenwood.

From memory it looks good, except the orange wires on the PAC are useless in C6. You need to connect the kenwood dimmer wire directly to the gray wire at the TC/AH button.
For your steering wheel button wires, if you can do it, you may want to move the orange wires in the PAC harness to pins A6 & A7, that way you won't need to splice into the car harness. If you can't get the pins to pop out of the pac harness, just connect any way you can.

Doesn't matter, as long as it's something that's turned on when your radio is on.
If you program one of the buttons as on/off you'll need constant or something off accessory power (like the main radio power feed in the harness), but if you only use volume/track buttons you can even get it from radio amp trigger output. They won't pull any current unless you push a button, so battery constant can be used also.
If you have the BT buttons on the left side of your wheel they turn into more radio control buttons, so you have 7 instead of only 5.
In my car I used the '1-6' button as mute, volume as volume, the 'up' as "track up", and the 'down' as "preset channel up". On Pioneers the track buttons change SIRIUS channels by one, but the preset buttons go thru my programmed presets. When listening to ipod the preset buttons don't do anything, so I used my up/down buttons as one of each.

Today I tested the radio and so far so good. I even got the steering wheel buttons programmed. Only problem I have now is how to install the bezel and radio. I could not figure it out. I have the Metra 95-3304 kit.
Thanks

I was expecting I had to attach the two sides to the radio somehow.
I did not connect the Dimmer to the TC grey wire. I set the dimmer to the NAV-Sync. Seems to be easier to allow the Day/Night dim to be controled by the NAV display settings. No need to splice the factory wiring.
Configured the Kenwood EXT Switch to control the NPP exhaust and it works
I would think someone could make a prewired harness and sell it to make it much easier to install. I know I would have purchased one and saved several hours of wiring.
Markcz you have been sooo helpful. I tried to get the same answers through the place I purchased the radio from but did not get the type of feedback you offered.

Got the radio installed and the steering wheel controls did not work I will call Axxess this week to see if there is a problem with the steering wheel control ASWC module. I noticed the Axxess web site does not list the ASWC as working on a 2011 Corvette

The 2011 buttons should be the same as all other C6, they prob just haven't updated their specs to include it.
Check your wires... The SWI needs +12v and ground connected. C1 plug A6 needs +12v. C1 plug A7 should be connected to the 'input wire' on the SWI. Plug the SWI output into the HU, then fire everything up and program it.

I had a 10 ohm resistor not a 10k ohm resistor when I was first trying to program the steering wheel control box. 
It programmed first try and I was able to move onto the next step in my install.
Thanks.
