Hi….I have a 2021 Tahoe High Country. I’ve had it 8 days. The RSE framework has been horrifying. Like you, we have a monster DVD assortment that lives in the vehicle. We were somewhat disillusioned to discover we were surrendering that. In this way, I had a go at utilizing Miracast/WiFi-Direct to stream directly from our telephones/tablets. It doesn’t work. An association has been difficult to make. Our telephones are running Android 11, so dislike we’re talking antiquated innovation. Along these lines, I tossed one of our Chromecasts in it. It works great…until it doesn’t. The framework haphazardly begins showing “no sign”. The solitary fix is a finished reboot of the vehicle. Our Chromecasts are old, so I proceeded to get a fresh out of the plastic new one at Walmart this evening. Same accurate conduct. Rankling. I’m a PC researcher, so dislike I’m mechanically uneducated.
