Have you tried bench testing it out of the truck with a battery and see if you get the same result?

I just got that same stereo and it did the same thing without the key in but with it in it works.

you have two wires. one is the constant hot wire that has to be hooked your constant power and the other one has to be hook your key so it only works when you turn the key on.

Usually, yellow runs to key, which I ran mine to the fuse box, and red is battery.
