I am inquiring about which is the best CANBUS Module for this vehicle. I believe it works with the GM LAN 29 Bit Data bus protocol. Here is a picture of the dash stack. 
If it is possible I would most be interested in allowing for the integration and display of the climate control information. The system is controlled via the data bus using button interface. Here is the picture of the factory interface. 
I want to do this installation with a DUDU 7 based head unit. Just doing research before making the purchase.
Thank you all for the information. I am excited to begin working and contributing to the community as soon as I get the correct hardware for the install. I will be using a Helix Ultra DSP behind the head unit and have been using a Joying UIS7862 unit for years now... I am ready for a new experience. It looks like the DUDU OS is the ticket.
Thanks again!
