2007 aftermarket radio sound not working
I have a 2007 Base Corvette non-bose and no onstar
I tried to install a Pioneer Nex 7000 with peripheral gmco interface"
Everything works fine however there is NO SOUND.
I tried everything I can but still no able to hear any sound from speakers.
All wires are connected correctly.
Can someone troubleshoot for me?

First things first, where are you located?
Did you add an amplifier? Did you do the work yourself or did a shop do it?
Are all of the connections from the new head unit connected to the correct wires from the Peripheral GMCO interface?
I just finished a install on my 11 vert using a PAC RP5-GM11 to keep On-Star and steering wheel controls. I put in a new head unit, amp and speakers. No issues with this.

Check/replace thge AMP (could be Bose) fuse under the hood (near the windshield, may be #30 or 31).
Did you connect the new HU blue "amp trigger" wire to the wire at B3 of the GMCO harness? If amp fuse was good, probably not.
Does sound come on when HU is on AM/FM but not the CD/iPod? If yes, then you used the wrong blue wire.

I didn't add an amp and I did it myself. Are all of the connections are to the correct wires from the GMCO to the head unit. I didn't connect the HU "amp trigger" wire to the B3 of the GMCO harness, I will look into all of that when I get home later today. Thanks for help, I'll let you guys know the result.

The stock amp is still what powers the stock speakers. The amp fuse has to be good, and the aftermarket radio needs to trigger the stock amp to turn on.
Look in your new HU installation instructions to find the "amp/remote trigger" (do not use the "antenna supply/trigger"). It should be blue/white in the power plug, but may just be blue and could be anywhere.
The GMCO should have a loose blue wire at pin B3 of the big plug that connects directly to the car. Connect your HU amp trigger wire to that blue wire. If you have trouble finding the blue B3 wire, on the car plug it will be a white wire and the plug is labeled A1-12 and B1-12.
Once you connect that wire your music will play
