The MyLink/infotainment console on my 2018 Traverse completely dropped out except for the reverse camera. Occasionally the back-light flashes for a second then drops to black again. No radio function and no Bluetooth connectivity. Also, both usb outputs will connect/drop repeatedly when plugged into a phone. I’ve attempted holding the home and fast forward buttons together, pressing the onstar voice button, disconnecting the battery for 20 minutes, and removing/reinserting the infotainment fuse. All with no luck. The next thing I’m going to try is opening the glove box to toggle the HMI cables, but if that doesn’t work then I’m out of ideas, aside from taking it in for service. I’m not sure it can be a screen power issue since the back up camera still works, so I’m thinking HMI, but is it possible to get a new cable if that’s the case, so I don’t have to replace the whole unit?
