change from stereo (GMC SIERRA to SILVERADO)

[adrz]

Good day,

I have a chevy silverado 1500/2015 (with stereo with small screen) and a few months ago I made the purchase of a larger stereo but it turns out that the stereo is a GMC sierra (turns on the button in red).

When installing it turns out that only the buttons work (raise / lower the song change volume) but the screen never turns on.

I do not know what the problem may be, I do not know if someone knows something about the issue or that a problem similar to these has already been solved.
