I have an 104 radio in my 2015 Silverado, which I also just bough an 8" display, thinking it would just be a swap form the 4" to the new 8". After some more research I found that I need to have the HMI programed for the 8" to work. I contacted MVI and WAMS, both companies that do the reprogramming. WAMS was more open to answering my questions but stared to give me conflicting info. Can anyone recommend another company. I did not like how MVI just became non responsive when I started to ask questions.
