What stereo did you install? Do you mean you had another aftermarket HU of your own? I don't actually care about brand, etc. Just curious if you swapped out one aftermarket for another - or if you had the factory unit for it.I bought this truck a week ago and it had an aftermarket stereo in it. They said they wired it to be constantly on because it wouldn't work otherwise. I replaced it with the stereo I had and wired it up correctly but it only comes on when the key is in the accessory position. When you start the truck it goes back off. Any ideas? Thanks!

Please give your description of "correctly". Our trucks kinda require an unusual installation (likely why the previous owner wired it the way they did).
There is a special harness that is usually required. There are ways around it, but it's not too simple. There is not a switched ignition feed for the stereo I think....that's why it is only working on ACC.
I'm going to assume the harness is simple and does not include all of the necessary connections.
The 2 preferred chimes retention modules are GMOS and GMRC units.
You can search the site for something like "How to retain RAP". It will describe how to wire your stereo to the battery so that the radio stays on until the doors open. Otherwise, you have limited functions of how it works. Unfortunately it's the GM design....believe it or not the Stereo is actually a hub for the BUS system.
If it fails again, then go another avenue. I don't know of different Scosche chimes boxes. I only know from reading that Schosche chimes for this truck are not the best suited. I do not know if one model works better than another.They did purchase an aftermarket stereo hook up after all. It was a black Scosche box. My buddy used to have a colorado and gave me the adapter he had instead, it's also a Scosche but it's blue I think (i'm colorblind). I just unplugged the old chime box and plugged the new one in. Works great now! Thanks guys.
