Does your HMI equipped GM Vehicle exhibit these symptoms:
If you answered yes to any of these questions you may have a faulty HMI Module! Faulty GM HMI (Human Machine Interface) Modules commonly cause black screens, “Waiting for Update Media” messages, flickering displays, loss of CarPlay / Android Auto and other ailments. These failures are frequently seen on Silverado, Sierra, Tahoe, Suburban, Yukon, Escalade, Impala, Camaro and more. Our replacement HMI units are factory-new, pre-programmed to your VIN and designed for seamless plug-and-play installation — no dealer programming required!

Diagnose Your Problem
Not sure what’s wrong? Start here to figure out exactly which part failed before you spend money.
“Waiting for Update Media”
The one definitive HMI failure symptom. If you see this message, the module is dead. No reset or update will fix it.
Black Screen Diagnosis
Black screen could be the HMI or the screen itself. Audio still working? That changes everything. Walk through the diagnosis.
HMI Module vs Screen
The #1 source of wasted money. Two different parts, two different failures. Replace the wrong one and you’re out $300-1,200.
