Putting JBL touchscreen from 2014 into a 2011 with JBL 6 cd changer!

I just swapped my old JBL with WMA MP3 and cd out for the JBL touchscreen, so far I’ve got the deck installed with the 20 pin cable connected. Also the satellite cable swapped over as well. I’m hoping the 20+8 to 28 pin adapter fits the rest of the necessary components for the steering wheel control. I also am wondering how to hook up the GPS cable, and how all that works, as well as the USB connector. If anyone has the part numbers or information I need it would be greatly appreciated, thanks!

 

This is the new JBL touchscreen, this is the original JBL OEM radio that was in my truck.
