Q
I have the pioneer MVH-S622BS in my 2007 Chevy 2500hd classic and my original antenna wire doesnâ??t hook up to the head unit. The hole in the head unit is too big. Will this allow me to hook it up?

It appears that the 2013 Camaro uses a different adapter - 12040EU10. You'll want to reach out to an Advisor before placing your order to assure you have all the items you need for your install.

Q
I got this adapter with my Pioneer DEH-X6600BT for install in a 2003 Toyota Matrix. I soldered all of the connections in the wiring harness that connects to the head unit and connected the antenna adapter, which seemed to fit fine. But now my radio reception is about half as good as with my factory stereo. Should I cut the end off of the adapter and solder it directly to my factory antenna cable? Is there something else I can try to improve reception? Thanks!
