New HMI

[José Daniel Gonzalez]

So I have posted on here I needed help with the screen in my 2017 Silverado and tried everything and nothing worked took it to the dealership and they said I needed a new HMI module and of course they wanted my soul to replace it haha so I went on to infotainment.com and bought one that was pre programmed to my trucks vin I put it in myself it wasn’t hard at all but now the radio doesn’t work at all and the screen doesn’t come on at all either. Am I missing something? Befor the new HMI I could control the radio with the steering wheel and the back up camera would come on .. now with the new one nothing comes on at all. I was told it shouldn’t need anything other than the new HMI … anyone know what I need ?
