My husband has a 2018 Silverado 1500 high country and his infotainment radio is doing the same. It bounces between screens, stations, disconnects Bluetooth, etc. it also causes the screen in front of the steering wheel to change too. His truck is way out of warranty (104,600 miles) so I’ve considered changing the head unit out for an aftermarket compatible one but I’m worried it’s a wiring issue as opposed to the radio unit itself. Your thoughts?
