I'd love to hear how this plays out. I drive a '19 1500 LTZ, bought my wife a '21 Tahoe z71, and damn I do like that screen and setup. The CT6 screen, I'm assuming it's similar to the Tahoe screen? Still a fair amount of fab required to make it look decent in the dash opening, right? Getting to the point where I keep everything as is and just keep enjoying my truck, and I'll just get the new stuff when I go to a 24 or 25 HD truck. BUT, I see hyou did the 2021 WAMS upgrade for wireless android...how challenging was that? Wouldn't mind getting the video rear view as well, if it's not a nightmare to upgrade.
Funny, putting the modular Pioneer DMH-WC6600NEX in my 57 Chevy BelAir seemed like a pain in the neck (still not done), but it's just fabbing up some parts to make it fit under the speaker cover in the dash and pop up. Having to mess with all the systems and controls on a new car is a nightmare!
