A:AnswerI have this radio, and I absolutely love it. It will work in your Denali. However, I don't think that you will be able to use the 6cd changer with you. Don't worry though. You can just transfer all of your music to a USB drive and plug the drive into this radio to listen. You will love this radio.
A:AnswerYou get these two inputs for (front and rear) cameras. They are ordinary female RCA plugs. From there it would depend on your stock setup. Hope that helps!
A:AnswerIt fits depending on what radio/ trim level the truck is.
There is a double din install kit that will replace the 4.3 inch radio
Also this radio doesn’t support the extra features that idatalink radio has.
I would get a good line converter such as an audio control lc2 or lc6 and keep the factory radio otherwise is an option
A:AnswerUsb comes with the radio and plugs into the back of it then you just plug a usb a or whatever cable into it. It then connects to CarPlay which you can play whatever you want on your phone or Bluetooth separately.
