So I am trying to install a Pioneer DEH-2100IB into my 2008 Chevy Cobalt LS and I am having issues. I have all of the "special" parts for it. All of the corresponding wires are connected, I have power and ground, but it won't turn on. When I hook the stock unit head back up it turns on, so I can't quite figure out what's going wrong. Any suggestions?

Double check all your fuses and wiring. Other than that, I can't help you. Did you buy the head unit new or no? Do you know for sure the head unit works?

You do have the accessory wire connected as well correct? Or do you have the LAN system harness?

Yea, I bought the head unit brand new and had all of the wires connected right. Turns out the dash harness the store sold me wasn't compatible so they refunded me and hardwired everything. It's up and running now. Thanks for the responses.
