HELP ME PLEASE my radio sucks!!!

[Luis A.]

Hey guys so about 4 months ago my radio started acting up, audio would not turn on, clock would disappear, XM presets would reset back to factory, and all the steering wheel audio buttons and center stack audio buttons would stop working, I cannot play any movies since my truck has the factory rear dvd system, and upon startup the screen would be black for however long it felt like it, I’ve already replaced the HMI, CD/DVD Player and LCD screen and none have solved my issue, I took it to Autozone a few days ago and the guy scanning it there says that his scanner did not pick up any DTC’s however he can establish signal with the braking system no problem however when he tried to do the same with the acceleration system and steering wheel audio controls it indicated a bad ground somewhere, can anyone help me please??????? Whether anyone can show me a list of all the ground locations for this truck or tell me how they solved this issue as well that would be great, I HATE this whole issue and I can’t even trade it in because of that, please help guys, I included pictures to give a better idea of what’s happening

Did you resolve this issue? Im having similar issues and was thinking about replacing the HMI. Sounds like that wasn’t the issue…
