2020 Sierra HD Rear Seat Infotainment System install

[Ryno12]

I’m looking to purchase the rear seat Infotainment system for my 2020 Sierra 2500 HD & I have a couple of questions for any of you that have these units.

Has anyone installed one themselves?

 

Does the dealership need to perform the install to be able to maintain the factory warranty of the system?

 

Is the DVD player contained inside the headrest unit? If so, do both headrests get a DVD player or do they share a single one?

 

Does the vehicle need any programming to perform the install?

 

 

 

 

Thanks for the help.

Did you ever find an answer to this or do this? I'm looking to do the same and was wondering the same questions.
